What's hell about the last chapter? (Other than the writing and the author's transparently obvious sexual preferences?)
Death? Hunger? Pain? That's small stuff. It is not Hell.
Hell is loathing your existence forever. The end point of every human is condemned to in that novel.

Do you fear death (not Death itself, but yes I do)?
What about it (bring unprepared, the pain of the process, fear of cowardice)?
