I think that the main 3 religions god is a spiteful one so that he can suck are negative energy and farm it to empower himself, that being reborn and forgetting everything is done on purpose so that we may feel the same pains over and over, that he make us fear him so that we can never escape him kinda like Stockholm syndrome, that when we dont suffer for too long god purposeful causes bad events so he doesn't starve from the lack of negative energy with in him.
