Due to the pain he's caused others? that's what he speaks of during the last scene, yet all i saw of him treating others bad was when he cheated on his wife.

I'm a fan of barkers and i always assumed that pinhead and his cronies don't come from hell, but from another realm thats unrealted to the christian hell. This film kinda threw that off track for me tho.

So apart from opening the box what exactly did he do to live/exist for all eternity in this self made hell?
