Gaara's theory and Neji's theory
 

they both have different theory
gaara have this "kill for a reason to live", while Neji had this "you can't change your destiny once you're born."
which one do you hate?

more of a creed than a theory. They both sucked though, which is why they changed. That and they met Naruto.

they should be glad they met naruto. without them think neji woul've turned out like sasuke and gaara....well gaara would still get no sleep

yea the both realized their theories is crap so they just threw them away
