i think Sauron really wrestling with wanting to be good is going to be significant to the story
He's Loki. Or Loki is him. He thinks dominion is the way to get the power he craves, but also serves in everyone else's best interests. And (not Loki) He's the greatest craftsman. Everything he creates is amazing, so why wouldn't everyone want his amazing stuff, his way, and his way only?
