Serial killer Edmund Kemper, at an early age, manifested conduct disorder symptoms. Kemper exhibited aggression and cruelty by cutting off the heads and arms of his sisters’ dolls and by torturing and decapitating animals. Cruelty to animals is part of the MacDonald Triad - a cluster of behaviours that suggest a child may be developing conduct disorder. Further, mutilating his sisters’ dolls demonstrates Kemper’s lack of empathy for his sisters. Finally, Kempers reason for killing his grandmother - “to see what it felt like to kill her” - supports the hypothesis that he was afflicted with conduct disorder of preadolescent onset. It is safe to say that in adulthood this could have developed into Antisocial Personality Disorder, as a person cannot be diagnosed with ASPD without the presence of Conduct Disorder before the age of 15.
