My interpretation of Hell is that it is always constant agony. No matter what you did, no matter where you go. There is no escape. There is no communicating with others. There is no bargains. You were a bad person, and for that you are thrust in the eternal fire.
I say there’s no layers, no demons torturing you, no escape. Just constant pain and agony, thoughts of regret, sorrow, and what you could have done better. You’re just in there forever no matter how bad you were, as long as you were bad.
