Suggest me some grimdark misery porn books

Hello, I'm looking for grimdark fantasy books that are straight up misery porn. Meaning no morality, no hope, all darkness ,bad all around and full on despair. I appreciate it, thanks!

Ps.: Please no Abercrombie, Glen Cook, Mark Lawrence, George R.R Martin and others that don't fit this category. They don't write full misery porn books, thank you!
