The problem is, no one can predict what people have by merely reading about them, nor by watching videos offering snippets of their lives. Also, no one is a one walking diagnosis. He could be cluster B, or cluster A (avoidant), or a mix, plus certain social issues, anxiety, and then, something else. On the other hand, his personality traits might be flattened, not enhanced. We have no information from specialists. We don't know if he was clean/sober, or substances were on board. We know nada to diagnose him.
I can see he was not the greatest speaker, and his actions indicate that he could not imagine the consequences of his acts, because he obviously thought the story would end differently, so there is a major thinking flaw somewhere. Also, he was born without morality in the bigger meaning of this word. But this is all. In terms of prediction, his story so far gives us very little.
