Killing in War presents the Moral Equality of Combatants with serious, and in my view insurmountable problems. Absent some novel defense, this thesis is now very difficult to sustain. But this success is counterbalanced by the strikingly revisionist implications of McMahan’s account of the underlying morality of killing in war, which forces us into one of two unattractive positions, contingent pacifism, or near-total war. In this article, I have argued that his efforts to mitigate these controversial implications fail. The reader (...) is left stranded: to reach plausible conclusions, Walzer deployed an implausible conception of our rights to life; McMahan’s more rigorous account of those rights generates untenable conclusions. Absent new developments, it seems that the prospects for grounding the ethics of war in individual rights are poor: any theory of our rights to life that is sufficiently indiscriminate to work in the chaos of war is not discriminating enough to be a plausible theory of our rights to life. Perhaps by rejecting the ideal of the rights-respecting war altogether we might develop an alternative theory of justified warfare, which marries theoretical soundness with conclusions that we can more confidently support.

There may be circumstances in which it is morally justifiable intentionally to kill a person who is morally innocent, threatens no one, rationally wishes not to die, and does not consent to be killed. Although the killing would wrong the victim, it might be justified by the necessity of averting some disaster that would otherwise occur. In other instances of permissible killing, however, the justification appeals to more than consequences. It may appeal to the claim that the person to be (...) killed has acted in such a way that to kill him would neither wrong him nor violate his rights, even if he has not consented to be killed or to be subjected to the risk of being killed. In these cases, I will say that the person is liable to be killed. Although I borrow the notion of liability from legal theory, and although much of what I say will be informed by the literature on liability in both tort law and criminal law, my concern in this article is with moral rather than legal liability.

In discussions of moral responsibility for collectively produced effects, it is not uncommon to assume that we have to abandon the view that causal involvement is a necessary condition for individual co-responsibility. In general, considerations of cases where there is “a mismatch between the wrong a group commits and the apparent causal contributions for which we can hold individuals responsible” motivate this move. According to Brian Lawson, “solving this problem requires an approach that deemphasizes the importance of causal contributions”. Christopher (...) Kutz’s theory of complicitious accountability in Complicity from 2000 is probably the most well-known approach of that kind. Standard examples are supposed to illustrate mismatches of three different kinds: an agent may be morally co-responsible for an event to a high degree even if her causal contribution to that event is a) very small, b) imperceptible, or c) non-existent (in overdetermination cases). From such examples, Kutz and others conclude that principles of complicitious accountability cannot include a condition of causal involvement. In the present paper, I defend the causal involvement condition for co-responsibility. These are my lines of argument: First, overdetermination cases can be accommodated within a theory of coresponsibility without giving up the causality condition. Kutz and others oversimplify the relation between counterfactual dependence and causation, and they overlook the possibility that causal relations other than marginal contribution could be morally relevant. Second, harmful effects are sometimes overdetermined by non-collective sets of acts. Over-farming, or the greenhouse effect, might be cases of that kind. In such cases, there need not be any formal organization, any unifying intentions, or any other noncausal criterion of membership available. If we give up the causal condition for coresponsibility it will be impossible to delimit the morally relevant set of acts related to those harms. Since we sometimes find it fair to blame people for such harms, we must question the argument from overdetermination. Third, although problems about imperceptible effects or aggregation of very small effects are morally important, e.g. when we consider degrees of blameworthiness or epistemic limitations in reasoning about how to assign responsibility for specific harms, they are irrelevant to the issue of whether causal involvement is necessary for complicity. Fourth, the costs of rejecting the causality condition for complicity are high. Causation is an explicit and essential element in most doctrines of legal liability and it is central in common sense views of moral responsibility. Giving up this condition could have radical and unwanted consequences for legal security and predictability. However, it is not only for pragmatic reasons and because it is a default position that we should require stronger arguments (than conflicting intuitions about “mismatches”) before giving up the causality condition. An essential element in holding someone to account for an event is the assumption that her actions and intentions are part of the explanation of why that event occurred. If we give up that element, it is difficult to see which important function responsibility assignments could have. (shrink)

In the theory of rights we repeatedly encounter the problem of reconciling someone’s having a right, with his properly suffering damage to the interest protected by the right. In the case of right to life, we have to assess numerous cases in which individuals are killed or allowed to die, and yet we wish nonetheless to affirm their right to life. These cases include killing an aggressor in self-defense, accidental homicide, terminating life-sustaining therapy, and capital punishment.

But what if in order to save 0nc’s life one has to ki]1 another person? In some cases that is obviously permissible. In a case I will call Villainous Aggrcssor, you are standing in :1 meadow, innocently minding your own business, and 21 truck suddenly heads toward you. You try to sidestep the truck, but it tums as you tum. Now you can sec the driver: he is a mam you know has long hated you. What to do? You cannot (...) outrun thc truck. Fortunately, this is not pure nightmare: you just happen to have em antitank gun with you, and can blow up the truck. Of course, if you do this you will kill thc driver, but that does not matter; it is morally permissible for you to blow up thc truck, driver and 211, in defense of your life. (shrink)

The various proponents of the DDA differ over how it should be understood. It might be thought that the distinction between doing and allowing reduces to the distinction between action and inaction. As against this, Philippa Foot has argued that some actions, such as pulling the plug on an artificial respirator, should be treated as “allowings.” On her view, the relevant distinction is primarily one between initiating or sustaining a harmful causal sequence, and allowing or enabling a harmful causal sequence (...) to run its course. The view that this is the proper interpretation of the DDA has been challenged by Warren Quinn, who argues that Foot’s distinction either fails to account for our considered intuitions in some cases or collapses back into the action/inaction distinction. Quinn offers an interpretation of the DDA that is closer to the action/inaction distinction, but in which intentions are made to play a significant role. (shrink)
