First I believe in Mysticism, and see deities only as superior beings whose existence we cannot yet comprehend, in other words ultimately indifferent.
So to my understanding (which is sadly little) that if you believe in a certain faith, you would end up in that afterlife. So Say you are Christian, then you will go to Christian Heaven because you are connected to that deity and will thus go to his dimension. If you have a different belief, then you will go to that afterlife. And with your believe, you will be judged to be derived further. In Christian's case, you will have to both believe in Christianity and be evil to go to Hell. And with those who do not have a particular belief, with varying degree of understanding and achievement in terms of spirituality, will be (which is really personal believe) free (and become a being greater than mortal), reincarnated, or bounded in this world (which is what we called ghost, or of course for other reasons such as Necromancy). This I believe also apply to anti-theists.
