You know, I've never been a fan of the idea that Hell was a place where the Devil ruled over sinners. This answer is going to dangerously skirt the religion line, and if someone takes offense, please let me know.
I was always under the impression that Hell was "the absence of love" (more specifically, the absence of God's love), and being doomed to that for eternity. I like to think that this absence of love includes the inability to feel, express, and receive love as well, but still have the memory of what it was. Those doomed to Hell (demons, devils, etc.) have no special super powers, but they have a lot of time on their hands. Given all that time, you'll want to interact with others. And the only interaction you are capable of is pain, trickery, deceit, etc. If you do that for several hundred years, you're going to get really good at it, hence the image of demons and devils as tempters and liars. They can't MAKE you do anything, but they can try to convince you that it's your idea.
Thinking of it this way might lead one to think that those consigned to Hell should be pitied, or at their very core are pitiable beings. Not the sort of pity you might have for a homeless person. You might be inclined to help the homeless person out of their situation. Those consigned to Hell are there because they earned that punishment.
I read a really entertaining short story once about a guy and his "friend" sitting in a coffee shop. The "friend" is enjoying a piece of pie when he suddenly announces to the guy, "I'm the Devil, you know." He then goes on to tell a fairly vague story about a woman he knew (he was drawn to her because of her faith). After that he asks the guy, "What did I do that was so wrong?" Now I'm sure the Devil in this story was working up some serious scam, but that last sentence draws me to it. What if he really doesn't know what he did wrong? What if part of being in Hell is the inability to understand why you wound up there? There is a note of despair there that has a certain ... appeal.
Meh. *ramble ramble ramble* Hope you get something useful out of that.
