Disclaimer: Tolkien may have thought the same thing... Kortirion articulates it.
I am the sum of other people’s decisions, I know that... Do I accept it? There seems little choice. Master Elrond might have ended it by forcing Isildur to let go... Gandalf might have made Bilbo relinquish it earlier... but who would have passed unseen to the Mountain? Even Frodo’s sympathy causing him to spare Gollum... would not have been a decision needed had the Elves not allowed sympathy to cloud judgement...
My doubt, my question... did the Valar know, did Eru know... what... devastation their decision to allow the music to become flawed caused? Or is all mere... accident?
