Abstract

This article is an examination of killing in war in its moral and normative dimension – with attention given to how killing affects the acting agent. The author argues against the commonplace belief – often tacitly held if not consciously asserted – among academics, the general public, and even – if surprisingly – military professionals, that killing, including in a justified war, is always morally wrong – even when legally sanctioned and necessary to avert a greater moral wrong. This critique of the “killing is wrong but in war it is necessary” trope is motivated in part by the large numbers of psychiatric battle casualties (specifically moral injury) suffered during operations in Iraq and Afghanistan, and which have attended military activity throughout history. The article approaches the issue through the field of Christian ethical reflection on just war. In building a moral framework for killing in combat, the article explores a typology of homicide, intention, double effect, love, and whether the attitudinal expectations of just warriors in the Christian tradition is realistic in combat. With this moral framework for killing in hand, this article concludes by drawing a critical distinction between moral injury and moral bruising.
