Synopsis
Naruto attempted to reason with Sasuke, although Sasuke was uninterested in returning to Konoha. As the two began to fight, Sasuke remembered why he had become so determined to gain power and kill Itachi. Sasuke had spent his childhood trying to win his family's recognition, although their interest was always focused on Itachi and his prodigious skills. Just when Itachi had begun to distance himself from the clan and Sasuke had started to enjoy his family's attention, he had returned home one day to find that Itachi had killed their entire family. Deciding to spare Sasuke, Itachi had given him words of advice: in order to become strong enough to kill him and avenge the clan, Sasuke need only strive for power. To help Sasuke down this path, Itachi had told Sasuke how to gain the Uchiha clan's most powerful ability, the Mangekyō Sharingan: to simply kill your closest friend. Having since come to find Naruto to be his closest friend, Sasuke prepared to do just that, finding the loss of Naruto to be an adequate payment for the strength needed to kill Itachi.
