Without the Spirit of Fire?

[Galadriel55]

This may sound weird, but I can see Feanor as the Melkor of Noldor. Melkor brings chaos to the Song of Ainur, he leads some of the down the wrong path...Same with Feanor: he's the one who causes the Noldor to be banned from Valinor, he leads them in a, in a way, rebellion against the Valar (Melkor rebelled against Eru). Both rebellions caused evil and both were otherwise pointless, unless you consider the butterfly effect. AND he is the brightest, most skilled, etc Noldor, just like Melkor was the most powerful ainu. There are probably other similarities between them, I' just too tired right now to really think it through.

Edit: they're also the most arrogant and not very wise - even though there are moments when they are cunning; yet still not wise.
