 One interesting question is whether the psychopath’s inability—or at least consistent failure—to respond appropriately to moral incentives is primarily the result of a motivational rather than cognitive failure: does the psychopath in some way know what morality requires and simply not care? If a positive answer is given to this last question (Fischer &amp; Ravizza 1998: 76–81; Nichols 2002), then it seems likely that the psychopath could be responsible for at least some of his bad behavior. And some have argued that even if psychopathy is primarily a cognitive impairment, it may still be the case that psychopaths possess a sufficient capacity for distinguishing right and wrong—or that they possess sufficient related capacities—to be held responsible, at least to some extent and in certain ways (Glannon 1997, Greenspan 2003, Maibom 2008, Shoemaker 2014, Vargas &amp; Nichols 2007). On the other hand, many believe that the psychopath’s capacity for grasping moral considerations is too superficial to sustain responsibility (Kennett 2019; Levy 2007; Nelkin 2015; Wallace 1996: 177–78; Watson 2011; see Mason 2017 for the claim that the relevant deficiency is one of moral knowledge rather than moral capacity). And still others have argued that even those who are fully impaired for moral understanding are open to blame as long as they possess broader rational competencies (Scanlon 1998: 287–290; Talbert 2014). However, the psychopath’s possession of these broader competencies has been called into question (Fine &amp; Kennett 2004, Greenspan 2003, Litton 2010).
