To follow up, in truth, Frodo failed. He was the Ring Bearer, but he didn’t destroy the One Ring, as he was tasked to do.....he was seduced by its power.
It was Gollum who destroyed the One Ring, though unintentionally.
I’ve always loved how Lord Of The Rings is quite likely the only work of literature named for it’s primary antagonist (Sauron); an unusual literary choice, but absolutely brilliant.
OK, it’s on. Frodo did not fail, if we use the generally accepted model for success. Let’s assume that in next year’s Super Bowl the winning quarterback throws an interception in the final seconds as he is driving his team down the field for the winning touchdown. He is a failure, correct? But, suppose that the cornerback who intercepted the ball immediately fumbled it, and an opponent picked it up cleanly and raced for a touchdown just as the last seconds tick away? The quarterback will still be a champion, will he not? He did all he could, and only succumbed for a moment when he was tired and beaten up. I recall that Frodo was in a similar state when he fumbled. Hardly a true measure of his purity I would think. The failure of the body is not synonymous with the failure of will... I opine in your general direction.
