A truly evil human created Hell after ingesting psilocybin mushrooms. Hey, I don't make this stuff up that's just what they told me. The prerequites here are that our consciousness is generative of reality and that a human can be "evil". I would think most of us on this site would agree that our consciousness does generate reality. I can imagine a lot of people would not agree that a human can be evil - I did not. To be evil a human has to be rather exceptional - highly intelligent, psychological stable - capable of completely understanding what he/she is doing. This is also necessary to actually have free will, I think. If one is acting out of poor childhood programing, emotional disease -whether psychological or organic - or from just say pure stupidity, can't have free will. The example that came to mind when the mushrooms said this thing about how hell was created was the difference between Hitler and Dr. Josef Mengele and I think they gave this example because it is so blatant - Hitler was not capable of true free will, no matter how evil was the outcome of his actions, he was not evil, he was sick but Dr. Josef Mengele was capable of free will and he was an evil man. I think a truly evil human is fortunately very, very rare. My guess is Cheney fits the bill, but not Bush.
