Itachi Uchiha つ﹏⊂

Sasuke was a happy child, eager to please and be worthy of his clan name.[19] One of Sasuke's most significant bonds is the one he has with his older brother, Itachi, who by merely being mentioned can elicit strong reactions from Sasuke's otherwise calm demeanour. Sasuke adored Itachi when he was a boy, enjoying his company above all others'; as an infant, he would cry whenever he was held by someone besides Itachi and would immediately be happy once held by his big brother again.But as he grew older, he learned to hide his feelings. He began to appear cold on the outside. But he was still kind, but he didn't show it.

Mikoto was a very gentle and kind woman, but could also be stern and strict when she needed to be, as seen when Itachi came back from the Academy and she told Sasuke that he could not play because he had homework. She loved her sons deeply and knew how to help them with their problems. Mikoto cared for and also held high respect for her husband as well and understood the importance of his position as the Uchiha clan leader and was a dutiful and loyal wife to him. She also gave Sasuke advice and tried to reassure him about his brother, Itachi.[7] She was a very good mother, seeing as how Sasuke was able to talk to her better than his father. At one point, in order to cheer Sasuke up, she says that when she and Fugaku are sometimes alone, Sasuke is all he talked about. Although she was Itachi's mother, she, like other clan members, grew suspicious of his strange behaviour toward the end, but regardless of that, she still cared deeply about her eldest son,

As leader of the Uchiha, Fugaku was focused on the clan's interest and welfare and had a strong sense of responsibility.[1] Fugaku stood out as one of the shrewdest security captains throughout the generations.[13] He was also shown to be highly observant, able to quickly determine when he was being spied on from afar.[7] His son, Sasuke, saw him as a stern and uncaring man while he was seen as a father-figure to the rest of the clan. As Itachi was his successor as head of the clan, Fugaku spent much of his time focusing on the development of his eldest and little time with his youngest. Sasuke trained constantly in order to get his father's attention and approval. While outwardly Fugaku seemed strict and neglectful towards his eldest and youngest sons respectively, coupled with his devotion and focus of his clan's welfare led him to seem hateful and non-negotiable, he was still a very caring individual to his sons.[11] According to Mikoto, when she and Fugaku were alone, Fugaku would mostly, if not only, talk about Sasuke. While always trying to motivate Sasuke to improve, he failed to see Sasuke's desire to be acknowledged as his son rather than compared to Itachi. He loved both his sons.

From a young age, Itachi was a quiet and insightful child, displaying unusual maturity for his age and knowledge of how to handle any situation. At the same time, Itachi sometimes displayed a childlike naivety in many everyday situations, and was eager to learn from his peers. [ 9 ] Itachi lived a distanced life, observing people and evaluating various ideas, trying to fully understand them and not taking anything for granted. [ 10 ] Due to his isolation, Itachi rarely became close to anyone, but this approach allowed him to think and act without prejudice, as well as evaluate things with an open mind. In the anime, Itachi inadvertently gained many friends and admirers due to his genuine concern for others, despite his aloof demeanor. [ 11 ] Itachi thought a lot about the nature of shinobi, as well as his home village, its origins, and its future. [ 12 ] In particular, this is why he did not develop arrogance due to his abilities and achievements, and did not allow his views to be influenced by emotions or the desire for personal gain. It is also why he never shared the fanatical fixation on his clan and the pride that came from belonging to it that was a common trait among many Uchiha; while Itachi loved his family and wanted the best for them, he understood that there were things far more important than the clan's aspirations. Although Itachi was a pacifist by nature, he understood that his own needs and feelings must take second place to more important things; with these convictions, he became a shinobi . Itachi trained to the point of exhaustion to reach the highest level as quickly as possible, and never complained about the difficulties of the shinobi life, motivated by a simple desire to be useful to others. His dedication to training bordered on recklessness; during solitary training, he used methods that involved mortal risk, such as dodging multiple kunai-laden machine guns. Thanks to his experience as a ninja, Itachi approached his problems with far less brutality than others, which satisfied his peaceful nature.
