Kinda moving back on topic: Ted Bundy was a fucked up human being by birth and raising. Erin Reed, I'm glad to say, is also a selfish prick but he has not yet (and unlikely will) engaged in murder, he's the kind who just uses people to both feel more powerful, boost his ego, and blend into society better. He's not at the kill point by a mile, he would be sentencing people to long jail sentences and executions, but he wants to be part of the ruling class party with respect and power given to him by a living society.
I may talk shit about Erin Reed, but Aaron is just a selfish insecure dude with a need for power and to feel something inside, followed by a porn changed coomer. He rates low on the depravity scale, mostly scoring points for grooming and lovebombing. Maybe he has some other good traits hidden, but I don't see them at the moment.
