Nice post
davem.
To continue my thought,
here is a link to the movie script where you can find the quote, "There will be no dawn for Men." Dawn will rise for Grima. Is he now of a different, more exalted type? Is he part of the force that will reshape all of Middle Earth?
Did he just help unleash the atomic bomb?
Or did he feel some remorse, even in this moment of grandeur, for his brothers, however remotely, and for the girl that he 'loved?' Do butterflies look at those who still crawl and feel a tinge of sadness, remembering what once was?
