The One Ring also affects animals. It affects everything from the literal angelic being who tells you outright that it would turn him into a tyrannical dictator. You would need to be above Sauron for it to not have any real effect on you. In an early draft it gets eaten by a fish in a river and the fish kills itself from the sheer madness of the ring. Now imagine being up 10,000 feet with the ring, its influence now acting upon creatures who you have no way of getting off of without falling to your death. The Eagles would have tried to kill the Fellowship somehow and if they made it to Mordor they would be attacked by Nazguls on Fell Beasts.
No matter what redditors try to say or state, every possible outcome was considered. The only way to truly destroy the ring was a stealth mission and casting it into the fires of Mt. Doom.
