I go in depth on this topic in my book, “We Are Their Heaven”.
Basically, there is a hell, a personal hell. When a person dies who’s innately bad and they have no remorse for crimes against humanity they find themselves separate from those who loved and were “good”. They “stew” if you will in their own dark energy and remain for lack of a better term in solitary confinement.
This has nothing to do with who has what religion or any religion for that matter it’s about how a person treated others in life.
