Unspoken ethical norms in war

I've had the privilege to interview more than 300 junior officers in Iraq and Afghanistan, and I have been very impressed and inspired by their deep commitment to leading their soldiers to fight morally.  Combat requires  moral decisionmaking--there's no getting around it--and our leaders overwhelmingly mean well.

However, I have also observed that many leaders and soldiers feel unprepared for the life-or-death decisions they have had to make in "gray" circumstances.  Their pre-deployment training consisted too often of black-or-white scenarios written by Army lawyers who've never had to make decisions in the fog of war. So, our soldiers learn by doing, trusting their gut instincts and character, and they generally do remarkably well.

The soldiers I interview describe their most uselful preparation for combat moral decisionmaking as being their reading of memoirs or other accounts of battle, and movies.  Band of Brothers, Saving Private Ryan, With the Old Breed, etc gave them a sense of the decisions they would have to make.

Of course, real accounts of battle are descriptive, not prescriptive...and real descriptions of war are full of events that would be war crimes by legal, media, and other dominant but uninformed-about-war parties.

In my interviews, which are one-on-one, confidential conversations in the war zone, I've noticed that soldiers who are doing the fighting have their own set of ethical standards.  In most cases and most situations, their ethical norms are consistent with what is expected publicly of them--be gentle with detainees, do not discriminate against local national civilians even if you know they support (not materially) the enemy, use gov't funds IAW all the regulations, leave interrogations to the trained interrogators, put the mission first, etc. 

Yet there are times and situations in which soldiers judge "what's right" on the ground to be much different than the public ethics.  Sometimes, soldiers "interrogate" detainees whom they are authorized only to tactically question; sometimes they use funds for purposes not authorized; sometimes they put more risk on civilians whom they know support the enemy; on occasion, they insure that someone they've detained will never able to kill the innocent again.

Each of these action violates the "public ethics" of the US military (and some the Laws of Land Warfare)...yet I've heard well reasoned, convincing moral arguments for them.  The problem is, our soldiers cannot ever say publicly what they did, much less offer their reasons, without making themselves liable to legal proceedings.  As a result, the next generations of soldiers will continue to be unprepared for the complex, difficult moral decisions they will face in war. It's a catch-22.

So, the profession of arms has two moral codes--the public one, based on black-and-white legal rules, that work much of the time; and a private code, known only by those who have to do the messy work of war.

It's not healthy psychologically to have made difficult moral decisions that you cannot talk about publicly for fear of being punished.

It's also dangerous to have such "unspoken" rules of war that differ from what soldiers are taught in formal training.  For example,inexperienced young leaders (2LT platoon leaders) can have trouble enforcing standards when they are not confident that they know the true standards.

I am going to develop a paper on this topic that I'll present at the New Mexico Military Institute in October, and I plan to refine it and present it again at the American Society of Military Ethics meeting in January.

More to follow, but I thought I'd put the ideas out there and solicit your feedback.  You can always write me privately at pgkilner@gmail.com  if you want to share your experiences and ideas on this or any topic related to moral decisionmaking in the military context.

Diminished moral responsibility of many enemy combatants

The straightforward examples used in my baseline argument for the moral justification for killing in war are not representative of many of the enemy combatants that we kill in the current wars. Many of those attackingIndigenous Security Forces or Coalition Forces (the good guys) are doing so solely to pay the bills, to put food on the table; others are uneducated and misinformed about the goals of each side in the wars. In other words, many of the attackers are not fully morally responsible for their actions. In terms of domestic self defense, they are more like: a drug addict who commits armed robbery and murder to finance his addiction; or a mentally disabled person who watched a violent movie, came across a loaded weapons, and is now “living the fantasy” by shooting innocent people; or like a man who mistakenly thinks that you raped and killed his mother and is coming to kill you.

In such cases, I think, we would say that using lethal force to stop the attack and protect the lives of innocent people is indeed still morally justified…but it is not satisfying, and is even tragic. When an attacker is not completely responsible for his life-threatening actions, it is sad—but nonetheless necessary and morally justified—to use lethal force in defense of the innocent.

The Justice of the War does matter

The editors cut a couple important paragraphs from the Army Magazine article. The paragraps address the effect that the justice of the war has on the morality of actions within the war.

"As you likely realized while reading the bubble theory, its approach to justifying killing in war requires that the soldier be fighting for a war that is just. This is a stumbling block for many military professionals. The bubble theory rejects the long-held tenet of the Just-War Tradition that soldiers on both sides of a war are “moral equals”—equally innocent of responsibility for the war but equally guilty of threatening each other. This claim of moral equality between unjust aggressor and just defender treats all soldiers as “innocent aggressors,” and thus reduces the “justification” of killing in war to the moral equivalent of gang warfare—no one is wrong because all are wrong, i.e., all soldiers have lost their bubbles. This waiver on soldiers’ responsibility for fighting may have had merit when feudal lords rounded up their serfs and led them into battle, but it does not reflect the educated, informed, morally autonomous citizen-soldiers of today.

We and our Soldiers cannot simply abdicate our responsibility to respect others’ human rights simply because we took an oath. Granted, given the huge responsibility we bear to protect the innocent, I do think that American Soldiers are morally obligated to fight unless they are convinced that a war is unjust. But I also think that an option should exist for selective conscientious objection. I doubt this would undermine good order and discipline. The patriots who volunteer to defend freedom will not abandon their fellow Soldiers without good cause. I have found most conscientious objectors to be woefully misinformed about morality in war. A healthy, ongoing conversation on the subject might actually enhance not only our Soldiers’ well being, but also recruiting and retention."

Ethics of Killing seminar at West Point

Department of English and Philosophy Seminar on “The Ethics of Killing”

Last Friday, 22 Jan, Dr. Richard Schoonhoven led a very interesting discussion on the ethics of killing, especially as it applies to war. This was the first of a series of Departmental seminars on the Army’s Professional Military Ethic. About 60 staff and faculty attended the 55-minute seminar.

Here are a few of my take-aways from the seminar:

First, it was validating. Richard didn’t put forth a theory or an answer to the question of the moral justification for killing in war; that wasn’t his intent. Instead, he laid out the many aspects related to the question—e.g., the problem of the innocent attacker, moral responsibility, “invincible ignorance,” the relationship of citizen and state, the connection (or not) of Jus in Bellum and Jus in Bello, noncombatant immunity. Yet, in almost every area of discussion, I felt confident that my approach to the morality of killing could coherently address the issues.

Second, I realized that much of the difficulty in making moral judgment in war is not a matter of developing a coherent set of moral principles; rather, it’s a problem of information. A soldier in combat rarely has complete situational awareness of the moral situation—the justice of the cause, the motives and intent of enemy combatants, etc. In contrast, we generally have much better information while making our everyday moral decisions. So, my insight was that we can develop a coherent combat ethics that assumes full information, yet we’ll have to deal with the complicating reality that soldiers will often act on incomplete or incorrect information. The category of morally excusable actions—those that are objectively wrong but not worthy of moral blame—is a BIG one in war.

Third, I was reminded of something that I’ve often talked about yet never written about—namely, that the justice of a war (jus ad bellum) is something that must be continuously evaluated. Whether or not a war was morally right to engage in in 2003, for example, is really unrelated to what we should be doing in 2010. A war might be just at its inception yet, as conditions change, become unjust to continue; and vice versa. The question is, “Given the feasible alternatives, should we (continue to) engage in the war?” Moral decisions are necessarily made with the information and circumstances of the moment; we can’t change the past, but we can and should resolve to do what’s morally right now and into the future.

Why study the morality of killing in war?

Why talk with our soldiers about the morality of killing?

1. Helping our soldiers understand the moral justification of killing is a leadership issue. Many soldiers who have killed in war are wracked by guilt when they should not be. When our soldiers kill justly, they ought to be able to live at peace with themselves. We, their leaders, are responsible for them killing; we ought to do our part to help them live fully afterwards.

2. Our soldiers arrive in the Army without any personal experience of killing another human being. As their leaders, we need to help them prepare for and make sense of the first-in-a-lifetime experience of killing a fellow human being. This contrasts with other, more frequent moral decisions. For example, by the time I turned 18 and joined the Army, I knew that stealing was immoral. Why? Well, when I was an 11-year-old boy, I shoplifted some candy. Almost immediately afterwards, I felt guilty and ashamed of myself. A year later, someone stole my bicycle, and I experienced anger and a sense of violation. So, by the time I became a soldier, I had a well-developed sense of morality about stealing. On the other hand, I had no experience with the morality of killing.

3. When it comes to killing another human being, our soldiers cannot trust their feelings. We human beings appear to be hardwired to feel guilty after being involved in the death of another person. For example, if you are driving a car under the speed limit and paying attention to the road, yet a pedestrian negligently darts in front of your car and is struck and killed, you will feel terribly guilty, despite the fact that you know you did nothing wrong. Apparently, playing a role in another’s death elicits guilt even without any wrongdoing. Sharing this observation alone is comforting to soldiers, who often wonder why they feel a sense of guilt even though they know cognitively that it was right to kill the enemy combatant.

4. Understanding the morality of killing in war empowers our soldiers to talk confidently with family, neighbors, acquaintances, etc., about the things the Army does. Within our military communities, we take for granted that wartime killing is morally acceptable. Other communities, however, do not necessarily share that assumption. All of our soldiers will one day retire or ETS. They will likely be challenged by the ignorant, indolent, and downright hateful towards the military. If we have not prepared our soldiers to respond to questions about wartime killing, we have left them defenseless.

Moral justification for killing in war

This is my latest version of laying out the argument. Feedback is welcomed!


A moral justification for killing in war
By Pete Kilner, 2009


Introduction:
The Army performs many of the same functions as civilian organizations, yet there is one absolutely unique and defining characteristic of our profession—we are organized, equipped and trained to kill people. As company-level leaders, we recruit patriotic young Americans to kill; equip them to kill; train them to kill; develop and issue orders for them to kill; issue fire commands for them to kill; and commend them for killing enemies of our country. We perform our duties well, and the American people sleep safely at night. However, we as a profession generally do not provide our soldiers with an explanation for why it is morally right for them to kill in combat. Consequently, many of the soldiers entrusted to our care suffer needless guilt after killing in war.

The purpose of this article is to offer you a tool—an explanation for the morality of killing in war that you can adapt for use in your units. This is a presentation I have given to units in the 82nd, 101st, 25th, and the Marines, as well as at West Point and ROTC programs. This explanation may not be the answer, but it is an answer to this difficult and oft-overlooked issue. Perhaps the most important outcome of having this conversation with your unit is a command climate in which your soldiers feel comfortable talking about killing and about the thoughts and feelings that killing provokes.

My story
Leader note: I have found it helpful to open the conversation by sharing my personal journey of thinking about the morality of killing. Every soldier thinks about this subject sometime, but relatively few talk publicly about it. If we want to open a healthy professional dialogue on a topic that is still somewhat taboo, we ought to set the example. Your story may be more grounded in personal experience and less academic (after all, I have never killed anyone), and that is probably more effective.

My personal interest in the morality of killing in war was sparked one night years ago when I was a pre-command captain in the 82nd. Rigged for a combat jump, I was waiting to load into a plane that would unload me and thousands of other paratroopers 400 feet above the ground. (The jump was later cancelled.) Amid the nervous chatter, one young trooper’s sincere question to a chaplain caught my attention.

“Chaplain,” he asked. “We’re gonna kill a lot of people tonight. Is that alright?”

“Of course it’s the right thing to do,” responded the chaplain with confidence. “We’re soldiers. The President told us to do it. That makes it right.”

I remember feeling profoundly disappointed in that response. I knew there had to be a better answer than that.

Two years later, I had the opportunity to re-visit the question when the Army sent me to graduate school to study philosophy. To my surprise and dismay, I could not find the answer. No one—not the chaplaincy, the SJA, the Army, the DoD, academia, not even my religion—provided a satisfactory moral justification for looking down my sights and placing two rounds into the head of an insurgent. Having enlisted as an infantryman out of high school and subsequently becoming an infantry officer, I had always assumed that what I was training myself and others to do was a morally justified action. I realized that I needed either to discover the answer or to find another line of work.

What I discovered in my subsequent research was that those who justify killing in war and those who condemn it approach the topic from very different perspectives. The Just-War Tradition justifies the moral permissibility of war at the international, state-to-state level. Although the tradition includes principles for individual soldiers’ conduct in war, it does not provide a moral justification for the combatant-on-combatant killing that characterizes war. In contrast, the War-Pacifist Tradition focuses its lens down at the level of the individual soldier. It argues that killing another human being in the context of war is morally unjustified and therefore wars among states are morally unjustified. I found both approaches to be inadequate. While the top-down justification did not go far enough in explaining why killing in war can be a morally right choice for the individual soldier, the pacifists’ condemnation of wartime killing was based on fundamental misunderstandings about war and soldiers. In my thesis, I combined a war-pacifist framework for justifiable killing with my own understanding of the nature of war to produce a moral justification for killing in war.

While writing my thesis, I happened to read Dave Grossman’s On Killing, which contains numerous anecdotes of soldiers reflecting on killing. Grossman, who has a background in psychology, makes sense of soldiers’ post-killing psychological problems by examining what happened to them in the experience. As an ethicist, however, I read the anecdotes with a different lens—focusing on what the soldiers had done, not on what had happened to them. I realized then that there might be a link between soldiers being able to justify to themselves the morality of killing in war and their post-combat psychological welfare.

Others' stories
Not everyone who kills in war is troubled by the experience, but many are. Because I have written about this topic, I receive many emails from veterans who have killed in war and from their families (more so from the latter). Their pain is palpable; listen in to these excerpts from a few emails.

From a soldier: “The last guy I killed was in a vehicle that came up to my checkpoint during an HVT raid. He tried to evade, I opened up as per ROE at the time, and shortly thereafter a couple soldiers with me began to shoot at the vehicle. I zeroed 28 rounds of a 30-round magazine into the passenger and driver. The driver was hit but not killed immediately, and he managed to back his car back into his driveway 300 meters away. What I’ll never forget about that engagement was listening to the family react when they saw the inside of the car and their loved one without a chest. I saw a counselor for about 6 months when I got back. I quit when I could start sleeping through the night without having to drink a six-pack beforehand.”

From a soldier’s mom: “My son is wrestling with what he did during his deployment. He was raised Catholic and was taught morality and values and we are big on the right to life. I am now trying to help him settle his conscience by explaining that killing in war is not the same as abortion. We, as a family, have been very active in pro-life activities and rhetoric. Now our son is really grappling with the fact that he took a human life, and I don't know exactly how to explain it, excuse it, or justify it. I want him to feel okay with what he did and about himself. I am avoiding the word forgiven, because I don't feel there is anything to forgive. We are supportive of his decision to join the military and are very proud of his accomplishments and ability to do his job effectively. I don't know how to impress upon him that killing in war is justified and not the same as murder and that he did what he was trained to do, and did a good job. Any words of wisdom would be appreciated.”

From a soldier’s wife: “My husband was in active combat in Somalia, Honduras, and Iraq. I think Somalia was the hardest for him. Yesterday I came into our room and saw him staring at the wall. He was pale, diaphoretic, and clenching his fists. I have never seen him like this. I asked if he was ok. This startled him and sort of "woke" him. He said he was fine and didn’t want to talk about it. Later he told me he has been starting to have dreams again and has had a few episodes of feeling charged/panicked, but he is able to regain composure and be fine. We talked at length for the first time about his dreams and his feelings about the people he killed while in combat. He carries so much guilt. He said at the time there was a moving target and he reacted. Now he remembers those same incidences and sees their faces. He is haunted by them. He didn’t want to talk to me or anyone else about it because he didn’t want to be looked at for what he had done instead of who he is. Is there anything you can recommend that I can do or he can do to help deal with his guilt? I love him dearly; he is amazing. I want him to be free. He has carried this for so long. He has been out of the service for 8 years now and it is still with him every day."

Stories like these are a call to arms to improve the way we train our soldiers. We teach our soldiers to kill effectively, so we should also teach them how to live with clear consciences after they have killed morally.

A moral justification for killing enemy combatants in war
Without further ado, here is a rights-based justification for killing. It does not rely on any particular religious belief, but it is consistent with Judeo-Christian assumptions about human rights as well as with principles of American civil law. I refer to it informally as the “bubble theory,” for reasons that will soon be obvious.

Our starting point in justifying wartime killing is the conviction that every person possesses the “right not to be killed.” Some would call this a “right to life,” but we really do not have such a right. If we are struck and killed by lightning or die of cancer, after all, our rights have not been violated. Why not? Because a rights claim is made vis-à-vis another person. No one has wronged us when we are stuck by lightning or develop cancer. Similarly, we do not have a right to speech; instead, we have a right that others not prevent us from speaking on certain topics. In this way, rights claims say something about what others should not do to us.

The ultimate source of our human rights is arguable. Some would say God, others cite human reason, still others refer to implicit social contracts or even man-made laws. But I hope we can agree that all persons do possess rights—whatever their source—and that the most fundamental and basic right is the right not to be killed, followed closely by the right not to be enslaved. Our system of government is premised on the belief that all people are endowed with the rights to life and liberty.

Rights are intangible, so it helps to use a concrete “visual” when we think about them. Imagine, if you will, the “right not to be killed” as a bubble that surrounds each person (see Figure 1). Each of us possesses the right that no one else “violate our bubble” and harm us. By virtue of being human, every person possesses a bubble. This is consistent with our moral intuitions. When we are walking down the street, for example, it would be morally wrong to physically assault a person walking past us. Why? In terms of this explanation, we would be violating that person’s bubble. He possessed the fundamental human right not to be physically harmed.

Yet we also know that someone can forfeit that right—can “burst his own bubble.” A right is a right as long as it does not violate the more fundamental right of another. Thus, we recognize that if a person intentionally violates (or threatens to violate) the bubble of another, he forfeits his own bubble (see Figure 2).

For example, if we are walking down the street and someone confronts us with a gun, we are morally permitted to use violence against the man to protect ourselves. Why? Because by consciously choosing to violate the bubble of another, the man had forfeited his own bubble of rights. The concept of forfeiting rights also applies to situations of coming to the defense of another. For example, if we witness a man pull a woman into an alley and continue assaulting her, we are morally permitted to use violence against that man to protect the victim, just as the victim herself is morally right to fight back against her attacker. Why? Because the attacker, by virtue of violating the bubble of someone who possessed it, had forfeited his own bubble, so our use of violence against him violated no right (see Figure 3).

It’s important to note that a just defender does not forfeit his rights when he attacks an unjust aggressor, as in the scenario above. The following scenario helps to clarify the rights of a defender. An armed bank robber has taken a hostage at gunpoint. By threatening the life of the hostage, the robber has forfeited his right not to be killed. A police officer then arrives at the scene and aims her firearm at the robber. Has the officer done anything wrong? No. Not only has the robber already forfeited his right not to be killed, but also the police officer has an obligation to protect innocent people, including the hostage. Would we say that the police officer, by virtue of “threatening” the robber, forfeits her own right not to be killed? Would the robber be justified in shooting the officer in “self defense”? Of course not, on both counts. The officer cannot violate the rights of someone who has already forfeited them. The moral inequality between the robber and police officer makes it morally acceptable for the officer to kill the robber, but not vice versa.
When fighting in a just war, a soldier is a defender. Soldiers continue to possess their bubbles as long as they direct violence only at those who have already forfeited their right not to be killed. Enemy combatants are the ones who have “lost their bubbles” by threatening the rights of those who possess them—non-combatants and/or our soldiers. Even if they are not personally threatening anyone at the time we engage them, combatants for an unjust cause are still morally permissible targets because they are operating as part of a larger organism—the unjust threat. There is a good reason why military uniforms include both the individual’s name and the organization/state in whose name he acts; soldiers act as both individuals and as elements of a collective.

Consistent with the rules of war, an aggressor’s forfeiture of rights is not permanent. The default setting for a human being is to possess the right not to be killed, so when a person is no longer a threat, he regains his right, his bubble. What constitutes a “threat”? A threat is someone who possesses both the intent and the capability to violate someone’s right not to be killed (see Figure 4). As soon as a person no longer has the intent or the capability to violate the bubble of another, he regains his own bubble and should not be killed. This is why it is morally wrong to kill a detainee or an incapacitated insurgent.

Limitations
That, in a nutshell, is the bubble theory of the morality of killing in war. I’ll be the first to acknowledge its shortcoming as a purely logical approach to an intensely emotional experience. Even soldiers who internalize this theory may still experience sadness, guilt, or shame after they kill in war. I doubt we would want it any other way; killing another human being is not something to be taken lightly or celebrated. Maybe the best we can hope for is that good soldiers’ bad feelings will be tempered by the knowledge that they did nothing morally wrong.
It’s also a fair criticism to say that the killing that takes place in war is often much more complicated than the situations described in this article. As one combat vet said to me, “It is almost never this simple. Very rarely is it a case of a white-hatted good guy shooting down the black-hatted villain who's been terrorizing the town. There are almost always shades of gray.” I agree, but we have to start somewhere. This article is intended to provide a “starter pack” of basic principles that you can utilize to initiate a deeper conversation in your units.

Perhaps the most tragic situations in war occur when well-intentioned soldiers mistakenly kill non-combatants. When unjust combatants refuse to wear uniforms, just soldiers bear the burden of identifying those who have forfeited their bubbles. Determining “hostile intent” is a big challenge for our soldiers, who often have to make split-second, life-or-death judgments with incomplete information. Good rules of engagement provide guidelines to assist that decision-making process. Nevertheless, given the complexity of combat, mistakes happen. The ROE will likely permit some immoral killing and condemn some morally justified killing, and soldiers will make well-intentioned, good-faith errors in distinguishing between non-combatants and combatants. It is critical that our soldiers understand that they are not morally blameworthy when they kill someone whom they thought had forfeited their bubble but in fact had not. Perhaps no argument will assuage their regret, but looking into their eyes and telling them, “You made the right moral decision with the information you had at hand” can only help. The vocabulary of rights and “bubbles” can help our soldiers make and justify their judgment calls, not only to 15-6 investigators but more importantly to their own consciences.

Implications
As you likely realized while reading the bubble theory, its approach to justifying killing in war requires that the soldier be fighting for a war that is just. This is a stumbling block for many military professionals. The bubble theory rejects the long-held tenet of the Just-War Tradition that soldiers on both sides of a war are “moral equals”—equally innocent of responsibility for the war but equally guilty of threatening each other. This claim of moral equality between unjust aggressor and just defender treats all soldiers as “innocent aggressors,” and thus reduces the “justification” of killing in war to the moral equivalent of gang warfare—no one is wrong because all are wrong, i.e., all soldiers have lost their bubbles. This waiver on soldiers’ responsibility for fighting may have had merit when feudal lords rounded up their serfs and led them into battle, but it does not reflect the educated, informed, morally autonomous citizen-soldiers of today.
We and our Soldiers cannot simply abdicate our responsibility to respect others’ human rights simply because we took an oath. Granted, given the huge responsibility we bear to protect the innocent, I do think that American Soldiers are morally obligated to fight unless they are convinced that a war is unjust. But I also think that an option should exist for selective conscientious objection. I doubt this would undermine good order and discipline. The patriots who volunteer to defend freedom will not abandon their fellow Soldiers without good cause. I have found most conscientious objectors to be woefully misinformed about morality in war. A healthy, ongoing conversation on the subject might actually enhance not only our Soldiers’ well being, but also recruiting and retention.

If the argument presented here makes sense, then we ought to do something about it. In addition to opening the conversation in our units, we can embed the ideas in our training. In AARs, we routinely ask questions like, “Why did you flank left?” and “Why did you decide to detain that person?” We can also ask, “Why was it morally right to kill that person?” As with anything else, our soldiers will become proficient through training. Killing is central to our profession, and it is a huge moral issue. We already train our soldiers to kill effectively; let’s train them to live effectively after they kill.

Take-aways for our soldiers
· Professionals of arms are entrusted to defend the innocent by using force.
· Every act of killing is a very serious, permanent action that requires moral justification.
· We kill only those who, by their own rights-threatening actions, have temporarily forfeited their own right not to be killed.
· Killing someone, even justifiably, is upsetting at some level. That’s normal and healthy. If the killing is morally unjustified, the psychological impact will likely be much greater.

Opening the conversation about the morality of killing in your unit
A lot more could be said, but this article covers the basics for launching a conversation in our units around the moral justification for killing in war and the natural feelings that killing stirs. A commander-initiated conversation will make your soldiers comfortable with the topic and provide them a shared vocabulary for talking about it. As Grossman says, “We are only as sick as our secrets.” A professional dialogue among you and your soldiers will be a lot healthier than the tortured internal monologues that so many soldiers are currently experiencing.

If you would like a copy of the full presentation, email me at pgkilner@gmail.com. I may be overseas for a few weeks in February with limited connectivity, so please be patient.
A final thought: It’s helpful to think of killing in war as akin to a doctor amputating the infected limb of a wounded warrior—it’s sad and painful, and it takes training and courage to do right, but is the morally right choice among lousy alternatives and therefore ought to be done.
