i used to hate sasuke. a LOT. used to bash him all the time and comparing him to naruto's Godliness personality. but then i grew out of it. realized that he was just a kid. conceited he may be, but given what he'd gone through at such a young age, it was kinda acceptable. to this statement some haters would claim that naruto had gone through basically the same thing but acted not like sasuke.
well guess what? different people has different personalities and that's what makes the world goes around.
wouldn't it be fucking boring not to mention painfully annoying to have billions of narutos running around all over the world, screaming "dattebayo!" at the end of every sentences?
think about it.
