All religions are a manifestation of "extreme" groups.
An extreme group is one that has all the properties of a group taken to extreme.
A property of a group is that it promises better welfare for its members. Most religions cannot realistically offer its members better welfare here and now, so they invent a future life and promise the better welfare in that, not just better but the extreme in betterness.
To make this promise even more attractive, they then invent a worse alternative, Hell.
If you are a Catholic, they go one further and tell you that you already in a much worse state than you thought which they call original sin, to make Heaven even more attractive.
There is otherwise no evidence for Hell except perhaps AM's trombone, and some ukeles.
