I was watching the recent YouTube video, “Why didn’t Elrond push Isildur into the Cracks of Doom?” by In Deep Geek. While the video is not about the question of this post there is this bit in the video which prompted me to write this post (a little after @3:30 in the video):
‘[This] is the One, and [the Enemy] is exerting all his power to find it or draw it to himself.’…
‘But why not destroy it, as you say should have been done long ago?’ cried Frodo… ‘If you had warned me, or even sent me a message, I would have done away with it.’
‘Would you? How…? Have you ever tried?’
‘No. But I suppose one could hammer it or melt it.’
‘Try!’ said Gandalf. ‘Try now!’
Frodo drew the Ring out of his pocket again and looked at it. It now appeared plain and smooth… The gold looked very fair and pure, and Frodo thought how rich and beautiful was its colour, how perfect was its roundness. It was an admirable thing and altogether precious. When he took it out he had intended to fling it… into the very hottest part of the fire. But he found now that he could not do so, not without a great struggle. He weighed the Ring in his hand, hesitating, and forcing himself to remember all that Gandalf had told him; and then with an effort of will he made a movement, as if to cast it away — but he found that he had put it back in his pocket.
Gandalf laughed grimly. 'You see? Already you too, Frodo, cannot easily let it go, nor will to damage it. And I could not “make” you — except by force, which would break your mind. But as for breaking the Ring, force is useless. Even if you took it and struck it with a heavy sledge-hammer, it would make no dint in it. It cannot be unmade by your hands, or by mine. - SOURCE
So, we see that from the very start Frodo could not manage to destroy the Ring no matter how much he wished to do so (never-mind that the attempt would fail…Frodo thought it would work). Over time, the Ring would only exert more power over Frodo and, I think we are told, the Ring’s influence increases the closer it gets to Mt. Doom and its creator.
So, was the whole thing a fool’s errand from the get-go? An impossible task that Gandalf had to know was impossible?
