But Sam's heart was pure.And this is really my reason for loving Sam the way I do...is he perfect? No. He certainly has his moments of blundering, and he's not always the sharpest knife in the drawer, but he is so GOOD at heart!
My favorite line is at the end of FOTR, "Don't you lose him Samwise Gamgee. Don't you lose him. And I don't mean to..."
Greater love hath no man than this...
I agree with you about Sam. Sam is the closest thing to perfect in the whole story, I think. He is ultimately the real hero that bridges the darkest chasm (when Frodo is thought dead, then carried off by the orcs, etc.). But it is the wonderful genius of Tolkien that his characters work together in a complex synergy, with all of the characters, especially Frodo, Sam, and Gollum necessarily playing their various crucial parts (as touching the Ring) at different times....
I guess what I'm trying to say is, without Frodo, Sam, and Gollum, acting in exactly the way they did (with all the complex interplay), there wouldn't have been produced the desired result of the destruction of the Ring....
