 To determine whether evil is qualitatively distinct from mere wrongdoing we must first understand what it is for two concepts to be qualitatively distinct. According to some theorists two concepts are qualitatively distinct if, and only if, all instantiations of the first concept share a property which no instantiation of the second concept shares (Steiner 2002; Garrard 1998, 2002; Russell, 2007). For instance, Hillel Steiner claims that “evil acts are distinguished from ordinary wrongs through the presence of an extra quality that is completely absent in the performance of ordinary wrongs” (Steiner 2002, 184). According to Steiner, the extra quality shared by all evil actions and lacking from merely wrongful actions, is the perpetrator’s pleasure; evil action consists in taking pleasure in doing wrong. No merely wrongful action is pleasurable for its doer (for more about Steiner’s theory of evil see Section 3.4).
