[LoTR] How would the world of Arda change if Melkor hadn't been evil?
gpt
Even Melkor's theme was born of the theme of Iluvatar. His evil has purpose, and no mortal nor immortal can fully understand the full theme of Illuvatar until it is revealed. Melkor was made the way he is for a reason. If Illuvatar had made Melkor differently, his entire purpose of Arda would be different. Since we cannot understand Illuvatar's current theme, we could not speculate one without Melkor.
