Make sure to consider how this character not dieing would affect the story! (e.g: if Boromir was never killed he may have been able to stop Merry and Pippin from being carried of by the Uruk-Hai, so they never would have met Treebeard)
@Arwen15 LOL, I think many people agree with you. I mean we never really got to see Sauron for the most part. I mean who would like him except for those people who have a giant, disembodied flaming eye fetish?
