Someone's mad cuz Sasuke>Neji, or that Sasuke is vital to the plot and Neji got killed by a toothpick.
Does no one here remember that ninjas regularly kill and torture each other for their village's or their own selfish needs and desires? Gaara did worse than Sasuke, and he's not considered a disgrace.
I don't recall Gaara committing treason or joining a terrorist organization.
No Sasuke has done much worse then Gaara, that's a ridiculous excuse.
And Ninja don't usually betray there own people like Sasuke does, so yes he is a disgrace.
