During the Ainulindalë, Iluvatar singled Morgoth out, and told him that all of his desires would have their uttermost source in him (Iluvatar), and that no matter what he did, or how much he rebelled, all his actions would follow Iluvatar's higher purpose for the world.
Keeping that in mind, wouldn't some things that Morgoth created have been beautiful? Granted, the dungeons of Angband couldn't have been what we would call "beautiful," but they did ultimately adhere to Iluvatar's "higher purpose," though we know not what that is.
