Same question how about serial killer as pshycopathic patient?
Serial killers often exhibit psychopathic traits, such as a lack of empathy, manipulativeness, and superficial charm. Research indicates that approximately 86.5% of serial killers meet the Hare criteria for psychopathy, with many also displaying sadistic personality traits[1]. However, not all serial killers are psychopaths; some may commit murders for reasons unrelated to psychopathy, such as revenge or emotional distress[4][6]. The relationship between psychopathy and serial killing is complex, with environmental factors and early trauma also playing significant roles in their development[4][5].
