Tortured Male MC getting revenge

Looking for books where the mc, through torture or other transformative events, becomes hell-bent on revenge. Would like to lean towards supernatural, monster-type fiction if possible. I finished reading Exoskeleton by Shane Stadler and need more like it. In a sense where the MC is rendered broken and a shell of his former self, with only anger left behind.

Edit: Should've mentioned I've read The Black Farm and it's sequel.
