Following his training under Orochimaru, Sasuke developed a very composed and detached demeanour, similar to Itachi, never letting himself get worked up in battle. In his pursuit for the power to take his revenge, whenever he meets new people, he makes an evaluation of their abilities: those he perceives to be weaker than himself he arrogantly disregards, giving them little attention. His only goal in life became to take revenge for his clan's deaths by any means.
