[the phantom]

There are others, Luthien and Galadriel included, who, while lacking in his raw power...

There's no need to go further than that, Sauce. I think raw power is what we're looking for, not virtues.

lmp, since this is your thread why don't you tell me, would a good description of what you are looking for be sheer amount of knowledge, strength of will, number of skills, strength of skills, ability to impact mind and matter, and ability in battle?

Not to mention, SPM, that Luthien was rash as well. She disobeyed her father and left the safety of Doriath to chase Beren, and almost paid dearly for her actions (Celegorm and Curufin).

Everyone acts unwisely under extreme circumstances, and Feanor's were arguably the worst any elf ever faced. He loved his father more than any son loved his father, he created the greatest work of skill ever- the Silmarils, and both his father and the Silmarils were stolen from him in a single day. That, coupled with Morgoth's efforts to corrupt him, was more than an elf could handle. After all, the Valar themselves told the Noldor as they left that they did not have the power to contest with Morgoth. If true, then surely there was no way Feanor could've remained unaffected by Morgoth's attempts to corrupt him, especially when you consider that marring Feanor was Morgoth's primary goal.

Morgoth was the most powerful being ever created by Eru, and so I find it difficult to hold the unfortunate events that followed against Feanor as much as many of my fellow Downers do. In my opinion, Feanor's fall was inevitable the instant the Valar allowed Morgoth to roam free and Morgoth resolved to ruin Feanor.

Fëanor, in my opinion, could probably "whup" either Lúthien or Galadriel- either physically, or in terms of persuasiveness and force of will. Or, at least, he'd probably be the best at it of the three.

I agree.

Luthien may have had Feanor eating out of her hand, if the sight of her could enflame lust in one of the most powerful beings in Arda, then I am afraid Feanor could have been vunerable to.

I doubt Feanor would be as vulnerable as Morgoth in this area. Feanor seems to love above all else things that were of himself- his father, his sons, and his crafts. If he had molded and sculpted Luthien from stone and she then came to life, I can imagine he would have quite a bit of love for her, but even then I doubt she'd have him eating out of her hand. He wasn't the sort to allow someone else to master him. Not to mention he already had a wife, and elves are by their nature not prone to straying.
