As his behaviour always got worse around alcohol and or other substances, I think that all the conjecture about his mental state should also include this.

Let's face it, he was not normal, he had episodes of complete tantrum which at his age was alarming. He had no awareness of how he was alienating himself and causing his own demise as people did not want to be around him when he was in full meltdown.

It's sad to see a grown man who has no empathy for others and can turn on anyone who gets in his way, as he did with Isaac and Kay. He had no compunction in doing it to them, even though supposedly their mate.

Then when he is told about it, he laughs and says it was because he wanted to.
