 In WAM, Anscombe also argued that human society is essential to human good, that the state is necessary for such society, and thus the state must have some right to use even deadly violence against those who attack it. (She defends some of these claims in greater detail in SAS.) But while pacifism is misguided, so too is the view that the state or its officers may do anything to defend itself. Killing is sometimes unjust, sometimes not. But warriors and police are often tempted to kill even those who are not unjustly attacking it, and, she holds, to kill the innocent deliberately is always murder, and, moreover, murder is always unjust.
