Killing a person is in general among the most seriously wrongful forms of action, yet most of us accept that it can be permissible to kill people on a large scale in war. Does morality become more permissive in a state of war? Jeff McMahan argues that conditions in war make no difference to what morality permits and that the justifications for killing in war are the same as they are in other contexts, such as individual self-defence. His view is not pacifist,
but it is quite unorthodox and has radical implications for the morality of war for example, that it's morally wrong to fight in a war that's unjust.
