I'm talking about the type of evil like in Lord of the Rings. The good side tend to fight against the oppression of the evil who want to do nothing but kill and start an "age of darkness", but what I've always questioned is what goes on in somewhere like middle-earth when there's nothing left but Lord Sauron and a bunch of orcs? Can they even still be evil and cause darkness when there are only evil creatures left, or do they keep a few hobbits around just so they can be evil to them?
This is one of my major annoyances when it comes to a lot of fantasy, the "dark side" always want nothing but destruction with no real goal after that, whereas the good side always have a bit more depth to their aims other than "win and conquer".
Sauron's goal was to wage war against the Maiar and Valar, and invade Valinor where he would meet the same fate as Melkor - cast into the void, with his forces scattered. The various players of the Third Age weren't fighting for 'good,' or 'evil,' they were fighting for the control of Middle-Earth. There was nothing ahead of Sauron except a quest for more power.
Saruman would have been destroyed regardless of other events, either by Gandalf, Galadriel, Elrond, or Sauron.
It should also be noted that Gandalf and the other Istari would have certainly been the equals of Sauron without the One Ring. Since Gandalf bore one of the Elven rings, Middle-Earth was in no real danger of falling to Sauron.
