[TheGreatElvenWarrior]

The points that have been made here about the powers of the rings are very good and I have nothing to add to them, however I do have a theory on Sauron's world view. Sauron was strong minded and opinionated, enough for him to be incredibly closed-minded. It wouldn't be too far of a stretch to me to think that he just assumed that everyone thought the way he did. Everyone wanted power first and foremost and had no other objectives in their lives. Sauron always held the belief, like was stated before, that anyone who got their hands on his ring would immediately want to use it. After all, he didn't have a whole lot of information to go off of to suggest otherwise.
