Abstract
In the wake of several high profile killings by offenders identified as 'psychopathic', Herschel Prins reviews the problematic conceptualisation of psychopathic disorder, provides historical context to the debate, and identifies aetiology and some key characteristics of the condition. He proffers suggestions for practice, concluding both that the concept of psychopathic disorder remains clinically useful; and that it is an essential prerequisite to effective management.
