Sasuke Uchiha's PersoNality

SASUKE UCHIHA'S PERSONALITY -

When he was a child, Sasuke was a very kind boy,
loving towards his parents and brother, and
respectful to his fellow clansmen as well as his
teachers. He was even very proud of being Itachi's
brother and Fugaku's son, famous for being
devoted protectors of Konoha, and he always desired to emulate them. His original dream was to
join the Konoha Military Police Force when he grew up, like his father. For this reason, he greatly
sought his father's approval and
acknowledgement of his abilities. After Itachi massacred the clan, Sasuke's innocence
was shattered, his ideals and personality changed severely, becoming cold, lonely, cruel,
cynical, somewhat arrogant, and with the next nine years of his life devoted to killing
Itachi.

When first introduced to Team Kakashi, Sasuke displayed great indifference to his team- mates. Feeling superior to all of them, including his teacher, Sasuke was unwilling to
cooperate with Naruto Uzumaki or Sakura Haruno, as he felt they would provide him no aid in killing Itachi. However overtime, as he spent more time with his team, Sasuke
began to lose some of his anger, caring more about his team than his revenge. To help
push him back into his desire for power, Orochimaru branded Sasuke with the Cursed Seal of Heaven during the Chūnin Exams to give him a taste of power. Although Kakashi Hatake sealed the Cursed Seal, as well as teaching him the Chidori in the hopes of deviating him from the path of revenge and instead protect his current friends with it,
Sasuke began to draw more power from the seal in the hopes of getting stronger, as
well as warp the Chidori into a blade to sever friendship.

According to Kakashi, Sasuke has both a superiority and inferiority complex, as he is
unwilling to acknowledge when someone is stronger than him, but obsesses when he
believes someone is stronger than him. For example, he was complacent with his rivalry
with Naruto when he believed he was stronger, but noticing Naruto's fast growth,
showcased in his victory over Sunagakure's jinchūriki, Gaara, who had previously beaten Sasuke, and his own quick defeat by Itachi on his return to Konoha, led Sasuke
to believe that his progression in Konoha was far too slow, which led to his defection to Otogakure to seek power from Orochimaru. Upon defecting from the village, Sasuke left with the Sound Four and travelled to the Land of Sound, only to lose the entire Sound Four to the Sasuke Retrieval Team and face Naruto alone at the Valley of the End , where Naruto attempted to save him from his path of revenge. Sasuke in turn planned to kill
Naruto, his closest friend, to awaken his Mangekyō Sharingan, but upon his victory he decided against it, instead vowing to beat Itachi his own way, not Itachi's.

In Part II, Sasuke's personality reverted to about the same as when he first met Team 7,
although his revenge against Itachi took precedence above all else, including his own
life. He also claimed to have cut all ties to his life in Konoha, believing that they were the
cause of his weakness, going as far as attempting to kill Naruto, whom he had spared in
their previous battle, to prove how detached he was. Despite this, Sasuke seemed unwilling to needlessly kill in his quest for revenge, and later when battling the Eight- Tailed Giant Ox's jinchūriki Killer Bee, Sasuke remembered Team Kakashi after witnessing his own team Taka each sacrificing themselves to help him.

Despite claiming earlier that he did not care if he had to sacrifice his body to Orochimaru as long as it served his quest for revenge, when Sasuke felt he had grown stronger
than Orochimaru he decided that to give himself up to someone weaker than himself
was insulting to the Uchiha. He proceeded to battle and absorb Orochimaru's
consciousness when the latter attempted to steal his body. This is only an example of
Sasuke's immense loyalty to his clan to the point of obsession; he remained wearing its
symbol on his back proudly while he refused to wear any other symbols such as a forehead protector. He also viewed anyone outside of the clan wielding the Sharingan as an insult, as the eye is a symbol of the Uchiha Clan's powers; while Itachi and Madara
complimented Kakashi's mastery over the Sharingan gifted by Obito, Sasuke expressed resentment at an outsider even possessing it; though slightly surprised at Kakashi for
awakening the Mangekyō Sharingan, Sasuke was not impressed, and stated that Kakashi should feel grateful to the Uchiha for the power. Sasuke showed further disgust
when Danzō had ten Sharingan in his arm, and an eleventh one in his right eye.

After his battle with Itachi, which resulted in Itachi's death, the
revelation that he had been ordered by the Konoha Elders to kill the Uchiha clan coupled with the fact that Itachi truly loved him,
Sasuke vowed to destroy Konoha to the last child for sacrificing
Itachi and the Uchiha clan for their own happiness. After he
confirmed the truth, Sasuke grew to loathe the village that he
once would have protected with his life. Although at first still
holding onto the notion of friendship and sparing the innocent, as time passed on with this new path of revenge, Sasuke has
grown much crueller and more ruthless, killing anyone who
stood in his way, sacrificing his own team to accomplish his goals and attempting to kill
his former team-mates and teacher, experiencing neither shame, guilt, or remorse for his
actions. He has also shown great rage whenever someone mentions Itachi in a negative
way, crushing Danzō with his Susanoo for speaking ill of his brother. After killing Danzō, Sasuke felt an exhilaration that he never felt before, and even sees killing members of
Konoha as a high, which lead him to vow to kill everyone in the village to finally
separate any connection of the Uchiha clan to the village, and in doing so purify the
clan's name. At this stage, it is likely that Sasuke's hatred and lust for vengeance has
passed the point of redemption, leading Sakura and Kakashi to completely lose all hope
in him. Even Karin, despite being obsessed with him, has given up being with him. The only person still having some faith in him is Naruto. Sasuke, in response, abandoned his
refusal to transplant Itachi's eyes into himself, in the hopes of destroying all that Naruto
stands for with his full power, hating Naruto more than anything for refusing to give up
on him. According to Madara, Sasuke alone is shouldering the entire hatred of the Uchiha clan.

. Also, for his entire life, despite being popular with females due to being handsome and
cool, Sasuke has shown absolutely no interest in any of these women, or their
advances, due to his all-consuming desire for revenge and power. Such girls include Sakura Haruno, Ino Yamanaka and later Karin. Even when Sakura's childish crush turned to sincere affection, Sasuke still did not return the feelings, though before he left the
village, he gave Sakura a genuine thank you. His disinterest in these women can turn to
ruthless and uncaring antipathy, expressed during his fight with Danzō, where he unhesitatingly pierced Karin just to kill Danzō, and during his fight with Team Kakashi, where he attempted to kill Sakura twice.
