Psychopaths are often portrayed in the media as criminal masterminds or even murderers. Some experts, however, argue that presenting them solely as ruthless killers is not an accurate portrayal of psychopathy and may unfairly stigmatize those with high levels of the trait. While the condition may involve criminal and antisocial behavior, such experts note, it is not limited to that, and many people high in psychopathic traits never engage in violence. Other experts caution, however, that high levels of psychopathy are a robust predictor of violent or criminal behavior. And while not all psychopaths are serial killers, some prominent serial killers were thought to have antisocial personality disorder, which is closely related to psychopathy.
