Could a person with antisocial personality disorder ever change ?

Personality Disorder: Difficulty question to ask, much less to answer. Research indicates that folks with this disorder are more resistant to changing for a variety of reasons. That doesn't mean that change isn't possible. Depends on the person's desire and/or motivation to change, and willingness to persist. And what the person might see what's "in it for them" as a reward.

Dr Berry agreed

Not likely : The hallmark of antisocial personality disorder is for the person to have basically no conscience. No sense of right and wrong or social morals. This type of personality disorder is especially resistant to treatment.
