Satan doesn't rule hell, he's an inmate just as much as the damned. No where in the Bible does it actually say Satan rules hell. That image is from John Milton's Paradise Lost where Satan says "It's better to rule in hell than to serve in heaven". The Bible says Hell was made as an eternal prison for Satan, demons, and unbelievers/sinners.

So Satan is less a prison warden and more the big tough inmate who makes you his bitch.

As someone who has studied theology I find this upsetting and hilarious. Though for clarity satan doesn't run hell, and doing good alone doesn't prevent you from going to hell.
