Because the uchiha were planing a coup' de tat on the leaf that is what madara predicted but the three elders planted itachi as a spy to keep the info on them Then itachi was received the mission to kill the entire uchiha clan. itachi kept sasuke alive not to measure his vessel it was because he just couldn't bring himself to kill his little brother.
Then he went to the third hokage he told him if you lay one hand on sasuke ill kill you instantly then he left without a word. He was to be considered a traitor due to the assaination. Itachi wanted sasuke to kill him so he could be known to revive his clan but itachi didnt expect sasuke tto join orochimaru which his plans were failed but sasuke still kills him then finds out the truth by madara
He was one of the Legendary swordsman like Zabuza Momochiwhich also means he is very strong,powerful,and he has killed a lot of people.
no itachi was ordered by the hokage to kill the uchiha clan but he could not kill his little brother but he beg the hokage to let sasuke live liar itachi would feel guilty of wiping out a whole clan
It is the hidden leaf village elders who ordered the murder of the uchiha clan, and sent itachi to do it. however Sasuke is not upset because his clan was slaughtered by itachi, but because after ordering itachi to kill the uchihas, the hidden leaf village elders forced itachi to become an outlaw. Sasuke (after learning itachi's true past from madara uchiha) is angry at the leaf village's mistreatment and rejection of his (newly) beloved brother.
Itachi left Konoha after he wiping his whole clan off xcpt his little brother "Sasuke". Itachi Killed clan coz, it was an order givn by the 3rd Hokage as he was afraid tht the Uchiha clan will break out a riot & conquer the Hidden Leaf Village. Itachi accepted the Mission undr 1 condition, tht ws "nt to kill his little brother". Itachi lovd his brother sooo much, he wntd him to become stronger thn Itachi. After eliminating the whole clan Itachi lied to sasuke to build hatred in Sasuke so he wud follow it & become strongr. Then Itachi ws givn a new Mission, tht was to "leak out the info about the AKATUKI". so he did it. But the Elders, Hokage & Danzo were the only ones who knew truth about Itachi in the leaf. They Kept it as a secret for the whole time. Itachi Returnd to the leaf aftr the 3rd's death, coz only to remind Danzo & the elders tht he ws alive & they Stil shud keep it as a secret. Itachi fought sasuke almost BLIND during their last battle. Even thn Itachi nvr stoppd lovin his brothr.

the 3rd hokage
to test his abilities
itachi killed his clan becasue it was an order from the konoha council. (third hokage, and the village elders) they thought the uchiha clan was planning a plot to destory Konoha and with fugaku, itachi and sasuke's father, being the leader of the clan's police force, he used itachi as a double agent, or coup-de-ot.

Itachi is the Uchiha who betrayed his clan. Because of that, he became missing-nin. He is partnered with Kisame, and can use Mangekyou Sharingan. He is killed by Sasuke.
Akatsuki didn't killed the entire uchiha clan. itachi Uchiha did. But it was a mission. Since Itachi Uchiha needed to kill the entire uchiha clan, Madara Uchiha knew everything what has happened. Sasuke Uchiha (The little brother of Itachi Uchiha) Is one of the 3 survivor's. When Sasuke killed Itachi, Tobi (Madara uchiha) told Sasuke the truth about Itachi. Since then, Uchiha Sasuke want revenge on konoha.
He felt happy, but then felt sad after he learned the truth of the Uchiha clan. Sasuke regret killing Itachi
Itachi Uchiha was secretly trained by Madara Uchiha(founder of the clan).Following Madara's footsteps he kills his best friend to obtain the mangekyo sharingan. To test the full power of the Sharingan, he attempts to wipe out his whole clan. This may not be seen but Madara helps him. The only reason that Itachi did not kill Sasuke is that the Mangekyo Sharingan is so powerful, it starts to cause blindness to the owner. So by letting Sasuke obtain Mangekyo Sharingan, Itachi is getting what he wants. The only way to reverse the blindness is to take one of your sibling eyes(what Madara Uchiha did to his brothers). Later in the series, Sasuke goes to the Uchiha shrine and reads that in a inscription on the wall. So Itachi killed the whole clan for a couple reasons: 1. To test the power of the Mangekyo Sharingan 2. He killed his best friend so the only way to get out of trouble is to kill his clan. 3.Itachi kicks butt =P (lol)
ya he killed his family and most of the clan i imagine so
It was said that Itachi had a lover, but it was never revealed who that was, it was revealed that he killed her along with the entire clan. And of course he loves Sasuke as his little brother.
