Abstract
Jeff McMahan has recently proposed what he calls a “combined liability-lesser-evil justification.” Its core idea is that the fact that someone has no right against the infliction of a certain lesser harm makes it easier for the necessity or lesser evil justification to justify inflicting a greater harm on him. This idea has been taken up by authors like Saba Bazargan or Helen Frowe. I will argue that McMahan’s basic idea is implausible to begin with, leads to counter-intuitive results, and seems to stem from a confusion between discounting the rights of wrongdoers and “subtracting” one right from the other. I then argue that Bazargan’s conclusion that minimally responsible threats can sometimes be killed as well as certain other conclusions that Bazargan regards as a particular advantage of his “hybrid account” are single-handedly generated by one element of that account, namely by the lesser-evil discounting view. Thus, the hybrid view is redundant. Moreover, both the hybrid view and the lesser evil discounting view of killing MRTs have strongly counter-intuitive implications. Finally, I show that Frowe’s application of the combined justification to non-responsible threats is entirely arbitrary and therefore useless. “Combined liability-lesser-evil justifications” should be rejected.
