Gaara was dead also..Though Gaara wasn't crushed. There has to be a reason he has a Sharigan if he isn't an Uchiha. And if he is an Uchiha there has to be a reason he only shows one eye and is still alive when all of the clan except two should be dead. The easiest way would be Obito but while I think it is I want Sasuke to find out that there is another clan of Uchiha not in Konoha so he's not the last and then he'll stop being so emo and junk and maybe actually become worth having alive.
I just think there is more to it than Itachi just wanting to prove his power to himself. Maybe if he killed just fighters or something but to kill the people who couldn't fight just seems odd to do if you want to prove you're strength. Unless you didn't want any witnesses but he left Sasuke alive and even said he did it. Nobody would have known Itachi had killed anybody if he had killed Sasuke but he left Sasuke alive. Unless maybe Itachi suddenly realizes he's become a monster after killing them but before Sasuke returns and doesn't want to kill himself but doesn't want somebody outside the clan to.
IN THIS NEW MANGA itachi kisame pein and the blue haired girl were all together near naruto and sasuke LIKE WTF and i know that naruto is a kage bushin and once it goes and like poofs away lol naruto will know and i think will either 1 STILL go for sasuke or 2 GO FOR ITACHI but i swear its gonna get SERIOUS.....
Sasuke better fail if he can't even beat Deidara when he has the element chakra that is stronger and no Mangekyo Sharigan. If he doesn't it's either going to be a clone or I may actually think Sasuke is being made into a god ...That or Itachi is weaker than Orochimaru and Deidara just his eye makes him able to beat them.
Maybe Itachi is already blind? Would explain why he always relies on his sharingan. And Kento, Sasuke did not and could not kill deidara and Orochimaru was on his death bed when he killed him, sasuke him self said the same thing and that it would have been different if he was at full health. I have no idea what the fuk is going to happen but Im loving the manga and cant wait for the next chapter.
