Sasuke Uchiha, driven by revenge, tracked his older brother Itachi to an abandoned Uchiha hideout to avenge their slaughtered family. Naruto and Sasuke begin to look for Itachi, both for differing reasons. Sasuke does it for revenge while Naruto does it in the hopes of it eventually leading him back to Sasuke so he can try to bring him back to the Hidden Leaf. In the interim, the arc shifts to focus on Kakashi's boyhood as a member of Team Minato, along with shining some light on his past teammates Obito and Rin.

Yes, Itachi Uchiha died from a combination of a terminal illness and extreme chakra exhaustion during his final battle with his younger brother, Sasuke Uchiha.Long before his fight with Sasuke, Itachi was suffering from an unknown, debilitating illness that he kept under control using medication. During their duel, his body was in an advanced stage of the disease. This, combined with severe chakra depletion and near-blindness caused by the prolonged overuse of his Mangekyou Sharingan, led to his death.Itachi meticulously planned his demise so he could die by Sasuke's hand, clear his family's name, and pass on his Mangekyou Sharingan abilities to his brother. He was later resurrected during the Fourth Great Ninja War via the Reanimation Jutsu, and his soul finally departed for the afterlife after he helped stop Kabuto Yakushi
Itachi Uchiha was not a villain, but a tragic hero who sacrificed his reputation and clan to prevent a civil war in the Hidden Leaf Village. Forced by village elders, he committed the Uchiha massacre, sparing only his brother Sasuke, and lived as a rogue ninja to protect Konoha from the shadows. Itachi's true motivations stem from his early childhood experiences in the Third Shinobi World War, which instilled in him a deep desire for peace. When his family, the Uchiha clan, plotted a coup d'état to seize control of the village, Itachi found himself forced to choose between his own flesh and blood and the safety of the entire village. To avert a devastating civil war and potential invasions from foreign nations, he was ordered to eliminate his entire lineage.He carried out this mission but deliberately spared his younger brother, Sasuke. Afterward, he bore the burden of being branded a traitor and international criminal, joining the dangerous Akatsuki organization only to keep an eye on them and ensure they did not target the Hidden Leaf Village. His ultimate goal was to make Sasuke strong enough to eventually kill him, hoping that by dying at his brother's hands, Sasuke would be hailed as a hero of Konoha.
