Is there any point in his life when we would have defined him as normal?

I'm sure there are school/medical records from his earliest years that confirm he's always had anti-social personality disorder and narcissism.

He's the only of 5 children shipped off at age 12 to "military school", i.e., juvenile delinquency. If it was for military reasons, he wouldn't have dodged the draft 5X. Imagine that ball of chaos in the household. Even racist authoritarian dad couldn't manage it.

have researched his childhood, his parents, his upbringing, etc. to get "get the whole picture of the moron and what could have caused him/it to turn out so terribly awful. Basically it came down to the fact that he was a little shithead and obviously has never changed. He is a bad seed through and through. As an elementary school teacher of over 15 years I can assure you that I can spot a bad seed a mile away. In fact, over the years I have told people, "Someday so and so will be on the news for doing something horrendous when he is an adult and I will say 'I knew it way back then' ".

that ship has sailed!
