You didnt read what I said, and youre ignoring his reasons he stated.
He could destroy Sauron without a sweat if he had access to his full powers. Limited as he was, he was only higher than humans and the power of Sauron would eventually take him over. He would try to weird the power for good but would slowly be possessed by it and he himself would be turned evil. He knew better than to try. Not that he didnt want to. The temptation was there.
Like I said, it was for the mortal creatures of middle earth to survive or die. Not for the gods to fix it for them.
The Gods arent manifestations. Theyre physical creatures in the world. Theyre just outside of it. They could come down and run wild all over Mordor any day of the week, but doing so their children wouldnt grow.
What I'm saying is how can a demigod become corrupted by a ring less power than the power he already has.
Like having a Mercedes and someone trying to tempt me with a Ford Pinto. ---
