ABSTRACTThe purpose of this article is to supply a justification in moral philosophy for considering the grossly depraved criminal to be less than a normally responsible agent. Decisions concerning the responsibility of a person depend upon our ability to act and react morally with that person. The argument is that when we reflect on the implications of (1) the moral role that desires play in excusing or condemning actions and (2) the minimum moral requirements of punishment, we realise that a moral community does not exist between us and the grossly depraved. That is, we cannot apply key moral categoriessimpliciter, including the notion of guilt.
