Bro this is literally the entire plot of the original trilogy. Boromir, Faramir etc all want to use evil for good.
Nonsense.
Nonsense.
In the movies, yes, but not in the books.
The movies completely reversed Faramir.
I was surprised as an adult when I first watched the movie that it didn't have this ending to the character arch, missing the final stage of the hero's journey.
