Moral judgement and moral conduct in the psychopath

The relationship between moral conduct and moral judgment was investigated by comparing moral reasoning of a psychopathic sample from a maximum security hospital for the criminal offender with a similar inmate, nonpsychopathic sample, and a group of "normals". Psychopaths obtained significantly higher scores on the Kohlberg scale of moral judgment than either of the other groups, for whom no differences were found. Results suggest the hypothesis that lack of guilt feelings in psychopaths facilitate the achievement of higher levels of moral judgment.
