Abstract
The increasing reported incidents of knife crime in cities and the release on parole of "rehabilitated" violent criminals are creating an unsafe urban environment. Such occurrences suggest that measures taken to address psychopathic-oriented behaviour may have been ineffective because the individual's degree of "moral deficit" is not fully accounted for in the application of specific therapies. This study developed a theoretical model of "moral deficit" that is aligned with the appropriateness of therapy, ranging from the extreme "classical approach" of total confinement justified by a belief in the incurability of psychopaths to the modern therapy that aims to reintegrate the psychopath with society using "moralizing therapy". Analysis of secondary data from extant literature was used to develop the theoretical model of "moral deficit". Secondary data analysis suggests that the extent of psychopathic "moral deficit" may be an important factor in the selection of appropriate therapeutic measures for psychopathy treatment and the rehabilitation of psychopaths as law-abiding members of society. We conclude that a specific type of psychopathic moral deficit may have an important bearing on the appropriateness of treatment. It is recommended that the treatment of psychopathy makes greater provision for the extent and type of psychopathic "moral deficit" in assessing the most appropriate applications for the treatment of psychopathy and promoting the safety of urban environments.
