An influential view in the ethics of self-defence is that causal responsibility for an unjust threat is a necessary requirement for liability to defensive harm. In this article, I argue against this view by providing intuitive counterexamples and by revealing weaknesses in the arguments offered in its favour. In response, adherents of the causal view have advanced the idea that although causally inefficacious agents are not liable to defensive harm, the fact that they may deserve harm can justify harming them (...) in the course of defending oneself. I argue that this strategy is ad hoc and leads to more problems than it solves. Once we allow normative facts outside our account of liability to affect a person's moral protection against harm, the lieability verdicts cannot tell us whether there is a relevant moral asymmetry between the victim and the target of defence. In conclusion, the causal view is wrong and causal responsibility for an unjust threat is not a necessary requirement for liability to defensive harm. (shrink)

What are the justifications for and constraints on the use of force in self-defense? In his book The Morality of Defensive Force, Jonathan Quong presents the moral status account to address this and other fundamental questions. According to the moral status account, moral liability to defensive harm is triggered by treating others with less respect than they are due. At the same time, Quong rejects the relevance of culpability to the morality of defensive harming. In this article I argue that (...) this rejection of culpability is unfounded and that Quong fails to establish his account as superior to the culpability account of liability to defensive harm.

Armed military interventions often inflict large amounts of collateral harm on innocent civilians. Ought intervening soldiers, when possible, to direct collateral harm to one innocent population group rather than the other? Recently several authors have proposed that expected beneficiaries of a military intervention ought to carry greater risk of collateral harm than neutral bystanders who are not subject to the threat the military forces are intervening to avert. According to this view, intervening soldiers ought to reduce the risk of collateral (...) harm to neutral bystanders, even if this means foreseeably imposing a somewhat higher overall number of collateral casualties among those for whom the intervention is conducted. This chapter raises a number of challenges to this view. Even if the beneficiary thesis is accepted with respect to discrete risk-imposing acts, it should not be with respect to risk-imposing strategies individuated on a war-by-war basis. (shrink)
