Galadriel and her redemption

[Nils]

Here are a couple of quotes from Letters on this topic:

At the end of the First Age she proudly refused forgiveness or permission to return. She was pardoned because of her resistance to the final and overwhelming temptation to take the Ring for herself.

~Letter 320 25 January 1971

and

Galadriel was 'unstained': she did not reach Middle-earth with the other Noldor, but independently. Her reasons for desiring to go to Middle-earth were legitimate, and she would have been permitted to depart, but for the misfortune that before she set the revolt of Feanor broke out, and she becme involved in the desperate measures of Manwe, and the ban on all emigration.

~Letter 353 dated 4 August 1973

I put the dates in because I believe they are relevant to Tolkien's evolving views on his myth. I believe this to be pretty good evidence that Tolkien's final view was that Galadriel did have a choice.
