I’m with Chyron on this one.
If Hell simply is separation from God (which is what Jesus basically said, and pope Francis too a few weeks ago), God does not torture anyone. He cannot torture people who are not near Him… they just suffer from being far from God, maybe because they decided to. Being far from God is their torture.
(I don’t say that I believe in this theory, but that does not prevent me from staying logical and knowing what is written in the Gospels)
