To avenge his brother, Itachi, since it was the konoha's higher-ups orders that Itachi annihilate the whole Uchiha clan, since Itachi's first priority has always been completing his mission, no matter what the cost...
It was Sasuke Uchiha in the naruto shipuuden series. Sasuke was fighting against itachi because itachi said he would take sasuke's sharingan eyes (itachi was going blind from the overuse of the sharingan.) but itachi never did, he wasn't serios about it, he just wanted to test sasuke's ability of facing him in battle. itachi is actually not even a bad guy, he was ORDERED to kill off his clan by the leaf village council of elders. Supposedly, the uchiha clan was going to take advantage of the leaf villagfe and caprure it as their own. itachi remained loyal to the leaf village and did what he was ordered to. but itachi never told this tio sasuke, so sasuke thought itachi did it just to test his own strength, and wanted to avenge him. itachi did not kill sasuke becaujse he really loved his little brother, and sasuke never knew that the whole time, even when he turned 15 and killed itachi, itachi still loved his little brother. sad story really... Itachi dies by an internal illness and the defects of overuse of the Mangekyou Sharingan.
Sasuke Uchiha is Naruto Uzumaki's childhood friend and team partner who lost his whole clan to a massacre by his older brother Itachi. He grows up to be obsessed with gaining power so as to get revenge upon his brother. This in turn makes him Naruto's greatest rival.
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)
