naruto - Why did the Uchiha Clan want to Rebel?

In Naruto, the entire Uchiha Clan are all slaughtered by Sasuke's brother, Itachi.

If they're so weak, why did they want to rebel?

Also the third hokage doesn't seem to be the kind condoning genocide. Does this make Konoha a socialist country?

Answer

1. Itachi is not an evil guy, he is a double agent. He does the killing for Konoha because the entire Uchiha clan was planning for a coup de'tat against the village and Itachi, who already have seen so much slaughter in the ninja war, does not want more blood spilled, so he kills everyone in the clan including his parents. The third Hokage was against the policy from the start and the killing took place without his permission. It was headed by Konoha elders, Danzo and ANBU under him.




2. Why didn't he kill Sasuke? Because he loved his brother and he couldn't kill him. He wants Sasuke to be an Avenger so he can become powerful and, because of his hatred for his brother, Sasuke can surpass Itachi. Finally Itachi plans their final battle so that by the time he dies he transfers his eye techniques. Yes, Sasuke gets the Mangekyo after that showdown and Yes, Itachi dies at the end of the battle.




3. How does Sasuke know about this ? It's revealed to him by the Head of Akatsuki (Remember Itachi and Kisame were going after Naruto) which is a terrorist organization for which Itachi was a part of. He joined the group to keep tabs on the organization and secretly keep his eyes on their plans with respect to the village. the reason he comes to the village when he fights Sasuke is because he wanted to threaten Danzo to prove to him that he is alive so he doesn't cause any concern to Sasuke.

Konoha is one among the major five Countries and throughout the series the crux of the matter is being a Ninja is about making sacrifices and how much one pushes themselves for the sake of the mission and their Village. Itachi loved Konoha. To him the village meant something more than his clan, except his brother.
