I have quite a lot to say about death, I have a...personalized faith of my own, I believe that once we die, we become one with the universe, you become a spiritual being and whatever physical concerns, like gender, age, and all that you had abandon you, you become a spiritual being and you become aware of every right and wrong you've done^^
As for a "hell" I don't believe there's one, everything everyone does is for a reason, so there isn't anything truly evil, just mistakes people make, that is just my belief however^^
