Itachi was ordered by the Hokage to kill his entire clan because he thought the Uchiha clan was a major threat to him. But only Itachi, the Anbu captain that was also involved in some way, and the Hokage knew that. Itachi was going to kill the entire clan, but couldn't bring himself to kill Sasuke as well, because he had a strong bond with him. So Itachi told Sasuke to hate him and to feed off of it, so he could get stronger. Itachi also told Sasuke that if he wanted to get the Mangekyou Sharingan he must kill his best friend. So Itachi ran away, and it is said he cried as he ran. Itachi joined the Akatsuki and waited for the day that Sasuke would come and kill him. Madara later tells Sasuke, after he kills Itachi, that Itachi planned to give him his eyes.
As some may think he killed his clan to test his limits and also Sasuke's.
It was more like a mission,
Ordered by The Third Hokage.
Though many may think he was evil and hated his clan,
When he was to fulfill the mission,
It Practically killed him inside.
He was in so much pain emotionally to have to kill his entire clan.
But he wasn't alone,
he was being trained by Uchiha Madara.
Who also helped him kill off the clan.
A Reason He Didn't kill Sasuke wasn't because It was to test his limits or so he could come back with revenge and hate to kill Itachi.
The reason was because he couldn't bring himself to kill His younger Brother.
wft? Naruto didn't kill itachi's parents. itachi killed the clan. u dodo brain. look it up
The only reason Sasuke killed Itachi was becasue Itchi killed nearly everyone in the Uchiha Clan. So he had to get his revenge. Kabuto really didn't have mauch of a part in that except for munipulating him into thinking he would help him get stronger to fight Itachi
In short: born into the Uchiha clan, became friends with Itachi Uchiha, gained the Sharingan and Mangekyo Sharingan, was assign to spy on Itachi by the clan when they where planing a coup and Itachi was acting strange, tried to stop the coup and got one of his eyes stolen by Danzo, gave his other eye to Itachi and killed himself.

Okay. ===SPOILERS for Shippuden=== Toby is a guy with a spiral mask with only his right eye exposed. However, he is actually Uchiha Madara, who was the strongest Uchiha of his time and who fought the 1st Hokage at the Falls. He has the eternal Mangekyo Sharingan, obtained by taking his brother's Mangekyo Sharingan. However, the reason why Itachi killed his clan is because his clan was going to have a military coup. As a 4-year-old, Itachi watched many ninja killed in the 3rd ninja war. So, he came to detest war. Were a clan so powerful as the Uchiha to rebel in Konohagakure, all of Konoha would be destabilized and another world war would begin to claim the land of Konoha. So, working as a double agent for the Hokage, Itachi was forced to kill his entire clan. However, he chose not to kill his younger brother whom he adored. Sasuke. Against his orders, he did not, and he begged the 3rd Hokage not to kill Sasuke. Itachi threatened Danzo as well. Itachi told Sasuke a lie so Sasuke would become stronger and would not be killed, and so Itachi left the future of the Uchiha clan to Sasuke.

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.
