I'm not sure how much of the ring's will was the ring's and how much was Sauron's. If Aragorn had the ring, would the ring's will be that of Sauron, Aragorn, or would it just weaken and all "wills" are belong to the current master. As long as the ring existed, Sauron would be lurking around somewhere. About the only thing I'm sure of is that if Aragorn had the ring, he also had the strength to become The Dark Lord of Middle Earth.
Isn't that what happened to the 9 kings who turned into the Nazgul. I know they didn't have the ring of power, but had the 9 rings... and they just became enslaved to Sauron's will and turned into wraiths
