Itachi Uchiha (うちはイタチ, Uchiha Itachi) was a prodigy of Konohagakure‘s Uchiha clan. He became an international criminal after murdering his entire clan, sparing only his younger brother, Sasuke. He afterwards joined the international criminal organisation known as Akatsuki, whose activity brought him into frequent conflict with Konoha and its ninja — including Sasuke — who sought to avenge their clan. Following his death, Itachi’s motives were revealed to be more complicated than they seemed and that his actions were only ever in the interest of his brother and village, remaining a loyal shinobi of Konohagakure to the very end.
From a young age, Itachi was quiet and insightful, showing noticeable maturity for his age and knowledge on how to deal with every situation. At the same time, Itachi was still fairly naïve as a child in many real-world scenarios and as such was willing to learn from his peers on how to differentiate situations. He lived at a distance, observing individuals and ideas without getting directly involved so that he could fully understand them. Although this approach prevented him from becoming close with many people, it enabled him to think and act without prejudice or preconceptions, instead evaluating things strictly on their own merits. In the anime, Itachi unintentionally gained many friends and admirers for his genuine concern for others despite his passive nature. He would think about shinobi and origins of the village and its future. For this reason, he never became arrogant about his own abilities or accomplishments; to which, most views or statements he made were usually well-based, seeing the situation for what it was. From this he had no self-righteous loyalty to his clan that was so common among the Uchiha; though he loved his family and wanted the best for them, he knew there were more important things than the Uchiha’s personal aspirations.
