I just saw this. I agree that he did hit the nail on the head with that final interview. What people are exposed to in their formative years as a young person determines their sexual appetite. Imo.

You can also quite clearly see the entity making an appearance in that interview when he is relieving a murder in his mind.

I think he was demon possessed.
I find Ted Bundy horrifying but also fascinating. Such a mentally deranged and depraved person.

If you guys haven't seen this you should watch it.
It is kind of profound. At least in addressing the ignored sickness in society.
