Despite leaving Frodo and Sam to finish what the Fellowship started, would Aragorn had he had the Ring been able to control it without falling to Sauron's will and becoming his servant? Was there a chance Aragorn could have been strong enough as a Númenórean from a royal bloodline of faithful Númenóreans, most notably Elendil and Isildur? (I know Isildur fell to it).
Is this what Sauron feared most about him, the fact that he was a strong-willed heir of the man who cut the ring from his finger? Could he in fact resist the Ring's attempt to corrupt him? Or would he have eventually caved and fallen like Isildur did?
