Abstract
After briefly narrating the evolution of Western ethical reflections on suicide and euthanasia, I argue that because people have a prima facie right not to be killed, it is usually unethical to kill anyone who poses no imminent lethal threat to others or who has not committed a capital crime. But I’m also persuaded that some instances of mercy killing in war are not only morally justifiable, they can be more ethical than allowing someone to die in agony and distress from their wounds. Thus I am uncomfortable with the current strict prohibition on battlefield euthanasia in the Geneva Conventions, which I think unfairly punishes some morally justified acts. But after considering the potential consequences of legalizing battlefield euthanasia, I conclude nonetheless that it is best to leave the prohibition intact.
