Because if satan had a "chosen people" they wouldn't call themselves "satan's chosen" would they? They'd claim theirs was the true god and the real (Christian) God was the impostor. Naturally they'd be involved with every form of degeneracy, subversion and evil around the world, and incapable of creating true art and beauty, only repulsive trash. And they'd be ugly on the outside too.
