From what I understand has been learned from near-death experiencers, there is no Hell as in the popular conception. There are, however, less good places in the Afterlife. There is also no external judgement, you only judge yourself during a life review where you feel the experiences of those you have hurt. You are supported with a sense of overwhelming love during this learning process.

I've never heard any word on the effect on reincarnation from those who believe they have been reincarnated. Well, that's excluding the zillions of charlatans and deluded.
