Abstract

If a threat is liable to be defensively killed, there is a defeasible justification for killing her. On certain prevailing assumptions about liability, which I accept, there are liability justifications for killing any number of minimally responsible threats, each of whom would otherwise kill a single non-responsible victim. Absent harms to third parties, these justifications appear, counter-intuitively, to be undefeated. I argue that this counter-intuitive appearance is deceptive.
