I have to agree that you guys are completely dicking up what the Neji/Naruto fight was about.
Both had seals that caused them grief.
Neji wallowed in his grief, raged against it, but in the end that was all he did- he bitched about it.
He stopped in his fight to whine instead of win- as he does, and he lost for it.
Naruto wallowed in the shit fate dealt with him, raged against it with pranks, but in the end, he takes what could have been a hand of shit and turns it into a pocketful of Aces.
That's the difference. Fate gave both a shitty hand to start with, but from there it was up to them.
Neji did nothing but whine, and so he lost the game of life.
Naruto took that losing hand, punched you in the dick and stole a full house from you.
My point is, Naruto got dealt a shitty hand that could have led to a shitty life or he could do everything he ever wanted with it- and he pulled it off motherfucking magnificently.
Neji got dealt a shitty hand and dealt the worst way possible. What if he garnered Hinata's support earlier? Bolstered her chances, maybe even sabotaged Hanabi? Neji is a huge reason for Hinata's crippling shyness, Hinata could have been the set, locked in heir years before she was, started helping her gather political power and completely eradicated the caged bird seal practice.
There's so much he could have done, but he threw it all away because he bitched instead of acting.
EDIT: I'm not trying to say, mind you, that you can always win no matter what hand you get dealt. I'm just saying that, in this instance, Neji's hand had a hell of a lot of promise- the privileged son of a major clan power in one of the strongest villages, massively talented with the skill to back it up?
There are people who would lie, cheat, steal, or sell their soul for a chance like that.
