Itachi did not lie to Sasuke when he informed him that your friend has to die for you to get Mongekyo Sharingan, but you do not have to kill your friend. All your friend has to do is die, or a carrier of Mongekyo can give it to someone. That is how Sasuke got his new power, from Itachi giving it to him.
Warning: This WILL give out information you might not want to know if your not far ahead!In the begining, Sasuke wanted to kill Itachi, his older brother, because he anihilated the Uchiha clan. Then Orochimaru came in the picture and Sasukes was mostly targeting Orochimaru. Eventually, Orochimaru took Sasuke in for care (and by care, I mean Sasuke wanted to be stronger, and Orochimaru gave him this opportunity, and Orochimaru wanted Sasuke to be his next 'vessel', but Sasuke didn't know this until later on.). While in the 'care' of Orochimaru, Sasuke is after Itachi, and secretly after Orochimaru. Orochimaru dies by Sasuke (and dies again by Itachi later on)- and Sasuke makes a team of other ninjas, and goes after Itachi. Itachi dies by Sasuke, and Sasuke finds out the truth of Itachi through Mandara Uchiha (also knows as Tbi, form the Akatsuki). Isntead of going back to the village that Itachi loved so much, and wanted to keep the peace, Mandara drove Sasuke in to a corner (not literally) that made Sasuke turn the opposite directions and target the Leaf village. Why, you wonder? Because the Leaf village wanted Itachi to sacrafice his village to pretty much keep the peace (or something..), and they sacrificed Itachi to do this mission. So now, Itachis after the Hidden Leaf!
mandara uchiha who also persudaed Itachi to kill his family wrong in order to get the mangekyou u have to kill your best and madara was not his best friend becuz hes still alive ---------- His best friend was Shisui Uchiha, he killed him in order to get the Mangekyo
yes i did not want to give spoilers but sasuke fights itachi and takes sasukes left eye and sasuke takes itachis right eye they keep fighting so finally sasuke kills itachi and does the head poke thing before he dies
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
Itachi and great thought sasuke tries to kill him from episode 1
To kill Uchiha Itachi, his older and hotter bro
because shisui was spying on itachi for the uchiha clan because the uchiha clan new that itachi was working with the leaf to try to overthrow the uchiha clan plus to get the mongekyou sharingan (you must kill your closest friend to obtain the mongekyou sharingan)
Sasuke didn't kill Orochimaru, he sealed Orochimaru inside himself. During Sasukes fight against Itachi Orochimaru got free but was sealed by Itachi. Later Sasuke used Anko's cursed seal to bring Orochimaru back.

No even though he is supposed to kill his best friend (naruto) to obtain the power to kill Itachi. His whole life was dedicated to killing Itachi and Naruto ended up meaning more than that. Sasuke DOES kill Itachi though, without killing Naruto

Sasuke wants to kill Naruto after killing Orochimaru, because he believed that killing his best friend/closest one/dearest to him (which was Itachi, his older brother's directions), will complete the transformation of his Mangekyou Sharingan. He will end up using it to claim more power, kill Itachi, and to cut off his bonds with Naruto. This opinion came to him long ago, after the assassination of his clan.
Because after Itachi finished killing the entire uchiha clan (except for mardara and sasuke uchiha) he tells him to kill his closest friend like he did and after so he must come to meet with him with the same sharingan he has, mangekyo sharingan. In order for sasuke to possess magekyo sharingan, itachi believed he must kill his closest friend as he did to ShiSui Uchiha and then he will be able to see him.] Sasuke grew up with a hatred for his brother and that hatred made him stronger. I dont want to be a spoiler though so i cant tell you what happens... Sorry lol but i hope this satisfy's you enough.
To kill his brother, and reserect his clan. According to him he is willing to do it even if he has to be consumed by hatred. I'm not sure what his goal is in the Shippuuden series. Cause Even after he kills itachi he finds out what really happened. And apparently desides to attack the leaf village.
