Okay, here is an exact quote I got from a website:
The Uchiha and Senju clans were always employed as countermeasures to each other, leading to hatred between the two that lasted generations. However, one day, a truce was called between the clan's leaders: Hashirama Senju and Madara called a ceasefire, founding the village of Konoha. However, the leadership was not equal and over time, the Senju politically dominated the Uchiha, segregating them into their own compound and looking down on them. Madara would have no such thing and in protest, attacked Hashirama. Madara used his ability to control the Kyuubi in the battle, but Hashirama's combination of being able to suppress it along with his Mokuton ensured his victory. Madara went into exile, creating massive unrest and tension. Years later, when the Kyuubi attacked, blame fell on the Uchiha clan once more. At this point, the Third Hokage, now called from retirement, reassumed his role and conferred with his advisors and Danzou. Outvoted 3 to 1 on the outcome, Itachi was chosen to be a mole among the clan. When it was confirmed that the Uchiha clan now planned to overthrow the current leadership of Konoha for their persecution and undeserved blame, Itachi was given the order to massacre them all.
Loyal to his village over his clan, Itachi carried out the orders. However, when it came to Sasuke, he couldn't bring himself to kill his younger brother. Fleeing, he made a demand to the Third Hokage, that Sasuke would never be told the truth of the matter. Itachi would be demonized and blamed for the massacre. Eventually, he would allow Sasuke to kill him so he could claim vengeance for both himself and his clan, all while blissfully ignorant of the truth. However, Madara wanted Sasuke to know the truth of the burden placed on Itachi and the atrocities committed by the leaders of Konoha. Weeping for the tragedy, Sasuke swore a new enemy, now desiring to destroy the people responsible. As a side effect of killing Itachi, Sasuke also awakened his very own Mangekyou Sharingan.
no he wants him to think that but itachi really loves sasuke he is just trying to protect him
yes he was alive but you know i hate this i wish itachi told sasuke to come back to konoha cause after that he killed itachi he hated konoha and his planning to destroy the leaf village Curse you sasuke!
actually, sasuke didn't kill itachi. when they fought itachi was hurt or sick, and he died. he never intended on killing sasuke. sasuke didn't know about itachi's past
Well in the beginning Itachi cares so much about his little brother and that's whyhe didnt kill him back then. But now i think him and sasuke are rivals now. --Animelover1234567
When Sasuke was little he had a loving brother, Itachi. Itachi was forced to kill his clan, but he refused to kill his brother, the konoha elders threatened to start a war if he didn't. Itachi hated fighting but he was forced to and he pretended to be evil so his brother would be known as a hero one day after he killed itachi. Itachi never hated Sasuke , infact cared about him more than the village and his own life. After itachi lets sasuke kill him (although sasuke didnt know this.) Madarra told him why itachi assassinated the clan and that it was the senju's fault and selfishness. Now sasuke is filled with revenge and plans to destroy The hidden leaf village.
ya he killed his family and most of the clan i imagine so
he hates itachi by the way who he killshe hates the intire village hidden in the leaveshe hates pein for destorying the village what sasuke wanted to do
Itachi let Sasuke kill him or he could have killed sasuke
yes his brother's name is Uchiha Sasuke and Sasuke's brother's name is Uchiha Itachi == ==
There is no "they"...only Sasuke kills Itachi. And, no, Sasuke is not friends with Naruto.
Because sasuke kept bugging Itachi to train him and tell him that he promise him that he will and Itachi said "not now maybe later sasuke"
Actually Madara did give sasuke itachi's eyes. In the latest manga madara transplants itachi's eyes to sasuke's.
