I don't believe in hell as Christians do. I believe when we die we are shown our life, and are shown our potential life, as in what we could have been had we lived up to our true potential. That's a true hell. After that, I don't really know if we are in some way punished or not. I do believe that if we mess up, we come back until we get it right. I also believe that those truly evil lose their existence. So all those suicide bombers who thought they were going to screw 70 virgins in the afterlife, well, they're gone. I think. I really don't know. I also believe that if we wrong someone, and are not forgiven by that person, both people have to come back so that the wrong can be righted.
Anyway, I don't think someone who commits suicide goes to hell. I believe they have to come back, possibly with the same flaws that led them down that path, so that they can overcome them upon a second chance.
