SASUKE VS ITACHI

The final battle between the last survivors of a proud clan...

Sasuke, a shinobi whose heart is filled with vengeance of his family and his clan. The boy who left his village, his friends, his bonds and even became a rogue ninja and collaborated to a criminal with sick thoughts(Orochimaru) and considered to let him take over his body. He became Orochimaru's apprentice to gain more power to achieve his vengeance.
Itachi, once known as the ruthless Uchiha who killed every single person in his clan. The best user of the most fearsome eyes, god of illusions, the youngest anbu ever lived... Nowadays he is known for his awesomeness, perfection, dedication, his self-sacrifice for the sake of his village even the shinobi world and etc. etc...

In this fight it was too obvious that Itachi could kill Sasuke in seconds. After the battle ended, and Itachi was dead, Obito revealed the truth to Sasuke and confirmed this opinion. Now it is a known fact that all this time what Itachi had been doing was to protect Sasuke and village in shadows. All the insult, beating, genjutsu he used on Sasuke after kiling his clan and their former counter, were just for an aim. And the aim was to remind Sasuke that he was weak, he had to be strong to get his revenge. And above all Sasuke had to be strong to protect himself after Itachi was gone. So, Sasuke kept his training, he was the best student in his school, he did well after becoming genin with his team. Then he continued his training under Kakashi's guidance. He developed chidori and used at the second part of the chunin exam. But it was not enough. There were stronger genins than him so he kept training. In their first encounter with Itachi after the massacre of their clan, Sasuke was beaten very easily by Itachi and he began to think that all his training was in vain. The gap between their powers was huge.Another trigger which caused Sasuke to feel weak was to see Naruto's rasengan's power on the roof of the hospital. Therefore, he decided to leave the village to gain more power to become subordinate to Orochimaru.

In their battle, Itachi continuously said that Sasuke was weak and he did not have the mangekyou, so it was not possible for Sasuke to win this battle. In fact, the reason that Itachi told Sasuke how to unlock the mangekyou when Sasuke was a child was to let him have Itachi's eyes after losing him and being killed by Sasuke.Therefore, Sasuke could replace his mangekyou eyes with Itachi's mangekyou to gain the eternal light. As it is known, the order of evolution of sharingan is as straight pattern 1,2,3 tomoe. Then mangekyou and after that eternal mangekyou. You may remember that Sasuke denied to have mangekyou by Itachi's way and did not kill his closest friend, Naruto at the final valley. Because of that, the order was spoiled and Sasuke came to fight with his 3-tomoe sharingan eyes.

Itachi knew that his time in this world was about to come to an end, so before dying he wanted to give his little brother new powers. During the fight Itachi's main goal was to give Sasuke the mangekyou and as we all know to unlock mangekyou  The Uchiha must lose someone precious. For Sasuke,The precious that we are talking about was Itachi. But there was a problem. The problem was the curse mark and Orochimaru in Sasuke's body. So, Itachi had to remove this problem from Sasuke's body. Because Orochimaru was a threat to his beloved brother, Sasuke's life. Even if Orochimaru was absorbed by Sasuke, he could take over Sasuke's body if the time came and Sasuke faced a strong opponent in a fight later on and used much chakra. So, He forced Sasuke to use all his chakra and deliberately continued to ask Sasuke whether he had any techniques or cards in his sleeve to be able to use against Itachi himself. Then Sasuke could not resist Orochimaru and let him emerge. When Orochimaru emerged from Sasuke's body,  that created an opportunity for Itachi to save Sasuke from Orochimaru he even said "You finally showed yourself". Once he was pierced by totsuka blade, he was sealed and Sasuke was saved. At his last moments he kept playing the villain and seemed to take his eyes. Sasuke was trembling because of fear. But Itachi said " Sorry, Sasuke. There won't be next time!! and made his atonement by being killed an Uchiha.
