Rescue and Necessity

Suppose A is wrongfully attempting to kill you, thereby forfeiting his right not be harmed proportionately in self-defense. Even if it were proportionate blow off A's arms and legs stop attack, this would impermissible you could attack by blowing just one of arms. Blowing violates the necessity condition on imposing harm. Jonathan Quong argues that violating consists a rescued: four A’s limbs self-defense rather than fails costlessly rescue three limbs. In response, we present cases which intuitively show constraint involves violation more stringent rescued.
