Melkor/Arda Marred or Remade

[Thinlómien]

We can surely say that Melkor was essential for Arda, most of the beautiful things there ever came to be and remaking of it. Without him, much would have been different.

Of course Morgoth would not know but then who can understand the intents of an ominipotent deity?

I very much agree with this.

I would like to compare Melkor to Judas in a way. They both became bad guys and did horrible deeds, because it was part of the big god's plan, and both suffered from fulfilling the part of the evil guy, though the part was essential: if not them , someone else would have made the evil deeds.
