From a young age, Itachi was quiet and insightful. 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. For this reason he never had the 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 aspirations.
Despite being a pacifist by nature, Itachi felt his own needs were secondary to the greater good's; to that end he became a shinobi. He trained tirelessly to improve himself as quickly as he could and subjected himself to all of the shinobi life's inconveniences without complaint for the simple motivation of being useful to others. Being so accomplished as a ninja enabled Itachi to approach problems less violently than others would, satisfying his peace-loving nature. These two extremes of his personality came into conflict as events moved toward the Uchiha Clan Downfall; he did not want to harm his family and sought a peaceful resolution, but knew that the path with the least bloodshed would be the clan's extermination. As the inevitability of the massacre became more apparent, Itachi's normally polite attitude to his clansmen became more violent, criticizing them openly and lashing out at them for the choices that sealed their fates and his own.
Despite the traumas he endured from killing his own family, Itachi did not blame those among Konoha's leadership who gave him the mission; though he did not trust Danzō Shimura on a personal level, he knew Danzō only had the village's best interests at heart. But Itachi – partly out of the necessity of his assignment to join Akatsuki – was greatly changed after the massacre, rarely if ever showing emotion. He became more prone to displays of force and permitted certain violent habits of his partner, Kisame Hoshigaki, under the pretense that it furthered Akatsuki's goals. Itachi could not and would not fully shake his pacifist ways, and would run from confrontation or rein in Kisame if the likelihood of collateral damage became too high for themselves or others. While Kisame would sometimes protest, he considered Itachi a good friend and would listen to his instructions.
Konoha's protection was always forefront in Itachi's mind, but it was his dedication to his brother, Sasuke, that took priority in every situation. From the time of Sasuke's infancy, Itachi tasked himself with looking after him. They'd spend whole days together in the woods around Konoha having adventures and accomplishing self-appointed missions. When Itachi began to become an accomplished ninja and took much of their father's attention, Itachi would make special time to fill their father's shoes for Sasuke's benefit, at times even refusing his father's wishes in order to make Sasuke happy. Sasuke, wishing to be just like his older brother, would often ask Itachi to train him in the ninja arts. Itachi would almost never do so, poking his forehead and promising to train him some other time.
It was Sasuke's safety that ultimately convinced Itachi to go through with killing the rest of the Uchiha, believing his own damnation was worth it if it ensured Sasuke's survival. Even though he did it for Sasuke, Itachi wanted to be punished for his crimes and selected Sasuke as the one to take vengeance against him. To push Sasuke in this direction, Itachi withheld the true reason for his actions and instead took on the persona of a man who had no love for his younger brother. Per the persona, Itachi cared about Sasuke only because of the eyes that he could take to gain Eternal Mangekyō Sharingan. His actions in Akatsuki were meant to reinforce this persona, and whenever he met Sasuke over the years he would taunt his weakness and encourage him to get strong enough to kill him. His plan was that, once he had been killed, Sasuke would be hailed as a hero. Itachi never wanted Sasuke to learn the truth surrounding the Uchiha's massacre, and if he did he hoped the memory of a hateful older brother would cause him to not believe it. Despite all his success as a prodigy, Itachi's sole failure was in his responsibilities as an older brother to Sasuke, something he wasn't able to acknowledge until after his death.
After he died, Itachi discovers that his plans largely failed; Sasuke is not a hero and he did find out the truth about what Itachi did. Naruto Uzumaki points out to Itachi the flaw in his plans: he had been trying to manipulate Sasuke rather than be honest with him and trust in his own strength. Acknowledging the mistake, Itachi is free to be himself instead of the persona he fabricated, being openly kind to others and displaying a dry sense of humour even in stressful situations. He is finally open with Sasuke when they meet again, admitting what he did and even sharing information Sasuke did not already know. He apologizes to Sasuke for all that he did, wondering if being up front with Sasuke from the beginning might have allowed them to avoid the Uchiha's destruction. In their final moments together, Itachi tells Sasuke he does not need forgiveness and that he will always love him no matter what.
Anko is easygoing, tomboyish, playful, stubborn, bold, rough, short-tempered and sometimes hyperactive. She has shown to be very knowledgeable and studious. However, she is also shown to have a bloodthirsty (in a literal sense) side. Anko has also shown a slightly sadistic side and is seemingly not the most sympathetic of people, which comes as no surprise, being the former student of Orochimaru. However, she does genuinely care about her comrades or people who suffer. Anko is also a very strict and blunt person, wasting no time in announcing bad news. She regularly makes sure to have at least basic knowledge of the landscape for which her next mission will take place. Anko is also highly self-confident in terms of her own abilities, frequently opting to face a powerful opponent single-handedly or continue a dangerous mission alone.
Anko greatly admired Orochimaru while under his tutelage, seeing him as a role model and was inspired to be more like him. After being betrayed by Orochimaru, Anko became enraged and carried a deep loathing for her former mentor. From there on, Anko continues to search for Orochimaru in hopes of taking him down, feeling that it is her duty as his former subordinate to stop him, even at the cost of her life.
Draco is the prototypical spoiled, rich brat; he believes that his family's wealth and social position gives him the right to bully those poorer than himself, such as Ron Weasley. He's a bigot and he's a bully, and in the most refined sense, he knows exactly what will hurt people.
Draco never feels remorse for his actions. He is someone who is very capable of compartmentalising his life and his emotions, and always has done. So he's shut down his pity, enabling him to bully effectively. He's shut down compassion.
Draco was indoctrinated with his parents' beliefs. There was a real moral cowardice in Draco, but that he was not wholly bad.
