The Christian hell doesn't exist. There are places in the astral that look like the Christian version of hell where Christians and others can be trapped there if they believe in it.
What we call Hell or Duat here is a physical planet somewhere in Orion, and that's the place where the Gods live. It's a beautiful place, and souls in Satan's side can stay for a while on an astral place there before they get reincarnated.
Contrary to Christianity, we also don't believe in an eternal afterlife, nor do we look forward to it. This is just a resting place between lives, and souls can get bored if they stay for a long time there, as it's boring if you don't have a physical body. This has been explained in ToZ.
