"The Good Kill examines killing in war in its moral and normative dimension. It argues against the commonplace belief, often tacitly held if not consciously asserted, among academics, the general public, and even military professionals, that killing, including in a justified war, is always morally wrong even when necessary. In light of an increasingly sophisticated understanding of combat trauma, this belief is a crisis. Moral injury, a proposed subset of PTSD, occurs when one does something that goes against deeply held normative convictions. In a military context, the primary predictor of moral injury is having killed in combat. In turn, the primary predictor for suicide among combat veterans is moral injury. In this way, the assertion that killing is wrong but in war it is necessary becomes deadly, rendering the very business of the profession of arms morally injurious. It does not need to be this way. Beginning with the simple observation-recognized by both common sense and law-that killing comes in different kinds, this book equips warfighters-and those charged with their care and formation-with confidence in the rectitude of certain kinds of killing. Engaging with Augustine, Thomas Aquinas, Reinhold Niebuhr, Paul Ramsey, Nigel Biggar, and other leading Christian realists, crucial normative principles within the just war tradition are brought to bear on questions regarding just conduct in war, moral and non-moral evil, and enemy love. The Good Kill helps equip the just warrior to navigate the morally bruising field of battle without becoming irreparably morally injured"--
