Why can't there also be a small but secretive handful of demons who aren't too interested in fighting? Their motives could range from "sick and tired of fighting for over a few thousand years", to "they've got human lovers", to "not very convinced that resurrecting Lord of Chaos will be the best for the demon populations(Fear that their culture could regress?)", etc.

I, personally, find this idea quite good, because it breaks with the usual clichés people use to have with demons.

When you find a big kettle of crazy, it's best not to stir it.
