What sort of creature would torture people with infinite pain for infinite time, simply for not worshiping them?

Christianity claims that you can steal, murder, rape children, commit any horrible act, and face no consequences as long as you repent: but if you spend your whole life helping others and being a decent human, but simply don't believe in God, then into the fiery furnace with you, for the rest of time!

It's sick and twisted. No sane person should believe in that torture pornography - it's a stain on humanity
