This article addresses a previously overlooked problem in the ethics of defensive killing. Everyone agrees that defensive killing can only be justified when it is necessary. But necessary for what? That seemingly simple question turns out to be surprisingly difficult to answer. Imagine Attacker is trying to kill Victim, and the only way one could save Victim is by killing Attacker. It would seem that, in such a case, killing is necessary. But now suppose there is some other innocent person, (...) suffering some entirely distinct threat, whose life one could save instead. Is killing still necessary? The seemingly obvious answer is “yes.” Killing is necessary since it is the only means to achieve the goal that stands to justify killing. The problem with this answer is that it presupposes a certain description of that goal as something like “saving Victim’s life” or “saving Victim’s life from Attacker.” Other descriptions are plausible, such as “saving a life.” On that latter description, killing is unnecessary in this case. The problem we are encountering is the problem of finding the right description of the goal of killing. Call this the “description problem.” This article sets out to solve the description problem and arrives at a radical conclusion. In a variety of cases, we should describe the goal of killing in broad terms, without reference to a specific victim or a specific threat. These broad descriptions—such as “saving a life”—make it easier to find relevant alternatives. Killing, it turns out, is much harder to justify than we might otherwise have thought. (shrink)

Because the poorest people tend to die from easily preventable diseases, addressing poverty is a relatively cheap way to save lives. War, by contrast, is extremely expensive. This article argues that, since states that wage war could alleviate poverty instead, poverty can render war unjust. Two just war theory conditions prove relevant: proportionality and last resort. Proportionality requires that war does not yield excessive costs in relation to the benefits. Standardly, just war theorists count only the direct costs: the death (...) and destruction wrought by war. This article argues that it can sometimes be appropriate to add the opportunity costs of a failure to alleviate poverty. Last resort is the condition that there must be no better alternative means of achieving the same just end for which the war is waged. This article argues that there are some cases in which alleviating poverty may constitute a better alternative. These are cases in which the most fitting description of the just end for war is sufficiently general that poverty alleviation offers a means to pursue it. The idea that poverty can sometimes render war unjust has, to date, been largely overlooked. It is, nevertheless, an idea with profound implications since, once taken seriously, war becomes much harder to justify. Wars that, in every other respect, seem just may prove disproportionate or unnecessary given the alternative of alleviating poverty. (shrink)

This essay argues that culpability and responsibility are independent notions, even though some of the same facts make us both responsible and culpable. Responsibility for one’s conduct is grounded in the strength of the agential connection between oneself and one’s conduct. Culpability for one’s conduct is the vices that give rise to that conduct. It then argues that responsibility and culpability for causing a threat are each grounds of liability to defensive harm independent of the other.

If the resources used to wage wars could be spent elsewhere and save more lives, does this mean that wars are unjustified? This article considers this question, which has been largely overlooked by Just War Theorists and pacifists. It focuses on whether the opportunity costs of war lead to a form of pacifism, which it calls ‘Opportunity Costs Pacifism’. The article argues that Opportunity Costs Pacifism is, at the more ideal level, compelling. It suggests that the only plausible response to (...) Opportunity Costs Pacifism applies in highly nonideal circumstances. This has major implications for Just War Theory and pacifism since it is only at the highly nonideal level that war can be justified. (shrink)

This paper challenges one line of argument which has been advanced to justify imposing risks of collateral harm on prospective beneficiaries of armed humanitarian interventions. This argument - the ‘Beneficiary Principle’ - holds that non-liable individuals’ immunity to being harmed as a side effect of just armed humanitarian interventions may be diminished by their prospects of benefiting from the intervention. Against this, I defend the view that beneficiary status does not morally distinguish beneficiaries from other non-liable individuals in such a (...) way as to permit exposing them to greater risks of being harmed. The argument proceeds in four steps. I first show that the BP can neither be grounded in liability-based nor in lesser-evil justifications for harming. I then argue that a standalone justification for unintended harming based on beneficiary status would face at least two critical challenges. The first concerns the BP’s applicability to collectives; the second questions the normative weight we can plausibly ascribe to beneficiary status when beneficiaries are such by virtue of being victims of wrongful threats of harm. I argue that standing to benefit is morally irrelevant when the benefit consists in the mitigation or prevention of wrongful harms, and consequently suggest that the BP may only serve as a distributive principle in allocating risks of harm if it is disambiguated in a number of critical aspects and applied in a more narrowlydefined set of circumstances.

It is sometimes suggested that victims of unjust harm should take priority over victims of other forms of harm. We explore four arguments for this view: that victims of unjust harm experience greater suffering; that prioritizing victims of unjust harm would help prevent unjust harm in the future; that it is good for perpetrators that their victims be prioritized; and that it is impersonally better that victims of unjust harm are prioritized. We argue that the first three arguments fail but (...) that the fourth argument succeeds. Moral agents have a reason to prioritize victims of wrongdoing because this secures the impersonal value of corrective justice. However, this reason can be activated differently for different agents depending on how they are situated relative to the wrongdoing, and it may be outweighed by other factors, such as the extent of the harm that could be alleviated.
