Satan is canonical for one thing in particular out of most things - he does not like humanity. Getting sent there isn't a fun field trip where you get to hang out with your buddies/partners in crime after the game is over, presumably.

Think of it more along the lines of you having a blinding hatred of mosquitos, and then they keep getting sent to you, and at the same time you're a very powerful, capable individual who can deal with hordes of mosquitos in fantastically wicked ways.
