If Sauron had been killed, or taken to the land of the Valar for punishment when Morgoth was finally beaten by the host of the Valar, would there have been an entire age of peace in middle earth, or would someone else who was evil have risen up to become a threat to taking over all of middle earth, and if so, who?
I dont know of another being that was left who would have been strong enough, and also good enough at conquest, and building and leading armies, etc.

I wasn't meaning that there would be complete peace without Sauron, because of the orcs and evil men that were around. But I think there is a big difference between general low-level threats, and what Sauron was doing to try and master all of middle earth. I wanted to know if anyone else would have been capable of attempting to take over lordship of all middle earth.
