Sam, Loyal friend, bravest hobbit, or just scared

[eldomeldo]

I wonder if any of you have thought about Sam's part in the fellowship. He was very loyal to Frodo and i consider that he was also very brave, but was his loyalty out of his love for Frodo and because of their friendship, or was it because he was scared of what would happen if he did not follow his promise through. I have always felt a great deal of sympathy for poor Sam, as he was often on the receiving end of Frodo's anger, due to the power of the ring.
