Possible Anti-social Personality Disorder

It is plausible to think that a serial killer would have anti-social personality disorder. Having this disorder gives them the opportunity to choose their personality and become anyone or anything they want.

Treatments

Talk therapy is the only therapy to try to understand how a serial killer really thinks. No medication has completely been diagnosed for patients because being antisocial has to do with their development when they were younger.
