Possibly the most powerful moral choice in all of the Lord of The Rings comes from Galadriel at the end of The Fellowship of The Rings, when Frodo offers her the ring.
The crux of Tolkien’s moral philosophy compressed into one line: “I pass the test. I will diminish.”
—
“And now at last it comes. You will give me the Ring freely! In place of the Dark Lord you will set up a Queen. And I shall not be dark, but beautiful and terrible as the Morning and the Night! Fair as the Sea and the Sun and the Snow upon the Mountain! Dreadful as the Storm and the Lightning! Stronger than the foundations of the earth. All shall love me and despair!”
She lifted up her hand and from the ring that she wore there issued a great light that illuminated her alone and left all else dark. She stood before Frodo seeming now tall beyond measurement, and beautiful beyond enduring, terrible and worshipful.
Then she let her hand fall, and the light faded, and suddenly she laughed again, and lo! she was shrunken: a slender elf-woman, clad in simple white, whose gentle voice was soft and sad.
“I pass the test”, she said. “I will diminish, and go into the West and remain Galadriel.”
The lore behind this is if you're powerful enough you don't just attract the wraiths, you actually can command them, & use the Ring to bend others to your will.
The Ring has the effect it does on Hobbits because they are naturally of the hiding & running away sort, not the powerful, willful sort.
You know how Saruman was able to build & command a huge army of Orcs, humans, & half-Orc-half-humans? Well it's not because he was paying them, it was because his will was in their minds, pushing them to follow his commands. With the Ring, he would be the single greatest power in Middle-Earth, & be able to wrest control of Sauron's own armies from him & use them against him.
Even someone like Boromir, who was a great captain of Men, could potentially actually wield the Ring to this purpose. The armies of Gondor would fight not just because they wanted to save their homes, but because the will of Boromir, amplified by the Ring, drove them forward. And he could potentially bring others to his side by force of will as well.
But the Ring is more powerful than anyone who would use it against Sauron. It's actually more powerful than the part of his will/spirit that was left outside of it. If they used it against him, it would corrupt them. Sauron would win in the end, even if the other portion of his spirit was defeated, because the Ring would take over the wielder & effectively Sauron would rule through the body of that wielder, be it Boromir or Galadriel or even Gandalf.
