maybe not hell (it depends on what kind of torture you get), but the lake of fire will be a place of eternal solipsism. you wont see anyone else down there, or if you do, it will feel like they dont exist. its similar in sensation to being surrounded by a million people but feeling totally alone. all your sense of "other people existing" will be gone. it will be just you down there suffering unimaginable agony for all eternity

the most brutal thing you can possibly imagine, and perhaps beyond imagination, is what will happen. you could have avoided it too
