Well, you can see in human relationships how some people treat the people they like and love, so with the devil, it could be only more so. I mean think of S and M couples as a fairly common counterexample. I just don't want to be the love of a Sadist's life.So you've got these two guys, ones good and ones bad, and they don't get on. One rules over the most of the entire universe and one rules in a place called Hell.
So if you steal and swear and act like a dick your whole life, and you go to hell for being 'bad', why does the Devil punish you?
Surely he should like you because you've acted up all your life.
Though I am sure I could happily go out to dinner and be friends with some of them.
So just multiply that with some hypothetical devil - like when he goes out to
dinner with you, he eats you. Because he likes you.
