[Gurthang]

I've heard this exact arguement in a different post, only about Gandalf. And they came to this conclusion. If anyone did have power enough to overthrow Sauron using the Ring, they would eventually become corrupted by it. Therefore, Sauron in the end would still have the mastery, for his Ring would prevail.

I've got an interesting thought. [take note, for this does not happen often] What would happen to an elf who put on the Ring. For it takes men and hobbits into the shadow world, but could it take an elf their also, or a dwarf even?
