 Other ambiguities concerning the meaning of the term ‘evil’ may be even more harmful. For instance, on some conceptions of evil, evildoers are possessed, inhuman, incorrigible, or have fixed character traits (See Cole 2006, 1–21 and 2019; Russell 2006, 2010, and 2014; Haybron 2002a and 2002b). These metaphysical and psychological theses about evildoers are controversial. Many who use the term ‘evil’ do not mean to imply that evildoers are possessed, inhuman, incorrigible, or that they have fixed character traits. But others do. If evildoers have these traits, and thus will continue to perform evil actions no matter what we do, the only appropriate response might be to isolate them from society or to have them executed. But if evildoers do not have these fixed dispositions and they are treated as if they do, they will likely be mistreated.
