 The moral competence condition on responsibility can also be motivated by the suggestion that impaired agents are not able to commit wrongs that have the sort of moral significance to which blame would be an appropriate response. The basic idea here is that, while morally-impaired agents can fail to show appropriate respect for others, these failures do not necessarily constitute the kind of flouting of moral norms that grounds blame (Watson 1987 [2004: 234]). In other words, a failure to respect others, is not always an instance of blame-grounding disrespect for others, since the latter (but not the former) requires the ability to comprehend the norms that one violates (Levy 2007, Shoemaker 2011).
