Those who support the usefulness of the term, such as Eve Garrard and David McNaughton, argue that the term evil "captures a distinct part of our moral phenomenology, specifically, 'collect together those wrongful actions to which we have ... a response of moral horror'." Claudia Card asserts it is only by understanding the nature of evil that we can preserve humanitarian values and prevent evil in the future. If evils are the worst sorts of moral wrongs, social policy should focus limited energy and resources on reducing evil over other wrongs. Card asserts that by categorizing certain actions and practices as evil, we are better able to recognize and guard against responding to evil with more evil which will "interrupt cycles of hostility generated by past evils".
