Which good guy (girl) do you least like?

This is probably pretty predictable, but...

Regarding Sam--I think you misjudge him if you think he was unforgivably mean to Gollum. He was sharp, certainly, on a number of occasions because he (sensibly, if not perhaps farsightedly) considered Gollum a threat and didn't like him. Perhaps Sam was, to some extent, responsible for the decision Gollum made to abandon him and Frodo to Shelob. In the end, though, Gollum made that choice. His evil actions over so many years had made it virtually (if not actually) impossible to choose otherwise. Notice, too, that Sam treats Gollum differently after he bears the Ring a while. Not that he dislikes Gollum any less, but he has more compassion. Sam's forebearance at Mt. Doom, as much as Frodo's earlier, permitted the destruction of the Ring. Take into account all the good Sam did--enduring well the most aggravating hunger, thirst, and fatigue and untold emotional pain to protect his friend and get the pieces in place so ME could be rescued. He could have turned back at any point along the road and had every reason to. He knew he didn't have much to offer but loyalty. Of all the hobbits, he may have been the most frightened by everything along the way and most aware of what he was sacrificing to do what he felt he had to--but he went on because he had made a commitment. He really comes a long way, considering how provincial and uneducated he was about the world at the story's beginning and how wise and good he has become at the story's close.

Again, just my two cents!
