The anime Naruto is a very rich world filled with interesting stories, interwoven characters each with their events augmenting the intensity of the plot and although some characters had a lot of wasted potentials especially during Shippuden, the ones who never lost the spotlight won the hearts of the viewers. One of such characters happens to be Uchiha Sasuke. Sasuke is one of the most complex character in the entire series as his existence fuels important and delicate aspects of the main character and the plot in general. He is pictured as the polar opposite of the protagonist - A talented ninja with a vengeful ambition. Sasuke is Naruto's biggest motivation right from ninja academy, the rival he intends to outdo as he was strong in every sector our hero was lacking including popularity with the girls.
Born into the most prestigious family of a very powerful clan known as the Uchihas, Sasuke was placed on the pedestal of expectations. The Uchihas were known for their visual prowess which also contributed to their unpredictable nature. As a child he absolutely adores his elder brother itachi- a calm, intelligent and strong teenager who would go through any lengths to keep his brother safe. However everything comes crumbling down when the very brother he idolizes murders the entire Uchiha clan (including their parents) right in front of him and urges him to get stronger just so he can take him down.
Boiling with pain, hate and rage, Sasuke concludes that his life's mission is one of a revenger with his brother's death being his sole objective. He concentrated on his ninja training, going the extreme mile of requesting for support from the copy ninja Kakashi Hatake who also possessed a sharingan ( the signature visual jutsu of the Uchihas) to boost his power stats . But when he realizes he was not achieving the necessary strength needed to defeat his brother, he deserts Konohagakure ( the village) to train under the tutelage of its traitor- Orochimaru.
During his time with Orochimaru, Sasuke obtains great powers which he uses to kill his mentor.
Finally ready to face his brother, he confronts him in an epic showdown to the death which inevitably ends with Sasuke victorious. Days after his victory, Sasuke discovers that his brother was not the heartless villain he thought he was. He was just an ordinary person who saw the negativity of war, hated the outcome and was trying to stop a coup headed by his father which would ultimately lead into a civil war.
Apparently the village leaders had forced him to kill the entire clan for the good of the village which he agreed to do with the exception of sparing his only brother. And then it dawned on him, Itachi was never the villain but rather a martyr forced to do the village's dirty work. This was the Pinnacle of his Pain, he was wrong about everything, he murdered his own brother for a lie, his whole world was imploding and he was experiencing a whole new level of torment.
Crippled by the revelation of his entire purpose being a lie, Sasuke chooses to destroy the one enemy responsible for all his pain konohagakure the village itself. With this newly found goal, he creates a four man team of misfits called The Hibi working with the enemies of the ninja world- the Akatsuki to achieve his objectives.
Driven by pain Sasuke is willing to go to any lengths to sabotage their plans only agreeing to a truce when the fate of the entire world is at stake. He joins the Allied Ninja force to confront Madara, the zestu force, the undead and finally Kaguya.
Moments after the fourth great Ninja War Sasuke launches full scale attack on the survivors convinced that the only way true peace will exist in the village is if he outs the previous hierarchy and becomes the leader ( hokage) of the village so that the tragedy of his brother will not repeat itself ever again. Confronted by Naruto his long time rival and supposed best friend the two engage in their final battle to weigh their convictions. While Sasuke was bent on eliminating his opponent, Naruto fought with the intention of knocking senses into the friend he has been chasing after all his life.
The heated battle soon ended with both friends losing an arm and Naruto showing his friend that he understands what he feels like to be alone, what it feels like to suffer, the pains everything and his choices will not give him the closure he needs but create a path that will only cause even more damage in the future. After a series of convincing Sasuke decides to surrender to the village, atome for past crimes and protect konoha as its hero in the shadows.
In the end Sasuke was able to achieve true happiness after years of unsettled rage. He gets married to Sakura his boyhood teammate and now has someone worth dying for - his daughter Sarada.
