Your opening gave the answer to whether he legitimately changed or not. Having been in the mental health field my entire career snd personally have interacted with others who have the three mental disorders you note. A key trait is master manipulation especially the borderline personality disorder. Feeling repentance could also be part of that as well as the dire self loathing he felt.

Only our creator knows his journey, soul plan and his afterlife. Who knows maybe he will return as a forensic psychiatrist or someone in partnership with a person with a personality disorder.

We love to cast blame, be disgusted by others behaviors, and stroke our own ego by saying we would never do that. Why are we fascinated by this apparent darkness?

Why would I want to put any attention and confirmation that this exists in our world? Am I living with rose colored glasses, of course not. I am responsible for who I hand with snd what I allow in.
