Perry - All three of those ideologies believe that the worst thing that can happen to a person is non-existence at death.
If the idea is that this is the only life I have and I should treasure it and the people in it, and I get the most out of it and I try to make it a better place before I leave it, I think that's pretty good. If the idea is that you will go on after you are dead and therefore you can treat the life, the world, and people you know as inconsequential compared to the hope of an afterlife, that seems like hell to me.
Regardless, you do know that there is a difference between what is and what you desperately want. Right?
