Feanor - Overrated?

[Dior]

In my opinion, Feanor only turned bad when he was such a jerk to his half-brothers. I think Fingolfin has to be my favorite elf in the Silm., and he actually tried to reconcile with Feanor, but Feanor just used him. I don't think that when Feanor refused to give the Vala his jewels it was that bad because at least it was just a pride issue. But when he was so treacherous with his brothers, he actually stepped over the line, and drew his sword on Fingolfin. It may have been Morgoth's lie spreading techniques, but Feanor was the only one to act so rashly. Because of his spirit, he was too easily influenced by evil, which made him an antagonist.
