As A Villain - Morgoth or Sauron?

[Belegorn]

A lot of people hate life because of suffering, and look forward to living in an afterlife, an ideal state such as heaven where there is only what is good, rather than enjoying life here on earth. Great pleasure and great pain. In the end, people should not try to avoid the later. Well that's neither here nor there as regards Melkor.

I think Melkor's presence extends through all of the Ages. Felagund felt his works effected the bodies of the Elves, and it certainly effected the hröa of Arda. He was too powerful to control. I think so powerful was Melkor that he never probably considered doing things as Sauron did. I just can't see Melkor making a Ring of Power through which he could control the Children of Eru. He would not even have to place much of his power in it to control the other Rings, if such a scenario played out where techniques that were taught to the Elves and used by them allowed him to create another Ring in like manner to be linked to and control them. Sauron obviously had to put an enormous amount of his own power into the Ring just so that he could control the Rings of the Elves. Dragons, Balrogs, and Trolls, these are creatures of immense power all serving under Melkor.

Basically his lust for the Silmarils "was a gnawing fire in his heart". [Of the Silmarils] I do not think the Silmarils for instance destroyed him like the pouring of his power into other things did by diminishing him and making him that much easier to control, especially when separated from all of his servants. I do know that he was impatient and Sauron would probably continue with projects he might have personally given up on.
