sasuke uchiha <2>

After the massacre of his clan at the hands of his older brother, Itachi, Sasuke's personality shuts down completely.
Cold and distant: He presents himself as an arrogant, serious boy focused solely on his training. He avoids forming emotional bonds because he considers friends a distraction from his true goal: revenge.
Uchiha Pride: He is aware of his natural talent and his status as the "genius" of his generation. He has difficulty accepting when someone (like Naruto) progresses faster than him.
He hides his warmth: Despite his tough exterior, Team 7 (Naruto, Sakura, and Kakashi) manages to soften him. On several occasions, he risks his life to protect them, demonstrating that deep down he still has a big heart.
2. The Obsessive Avenger (Naruto Shippuden)
When he leaves the village to join Orochimaru in his quest for power, his personality darkens significantly.
Absolute Focus (Tunnel Vision): He becomes calculating, methodical, and extremely detached. He doesn't mind being a criminal's pawn if it gives him the strength to kill Itachi.
Controlled Cruelty: At the beginning of Shippuden, Sasuke does not kill for pleasure or innocent people; in fact, he avoids unnecessary casualties. His brutality is strictly reserved for those who stand in his way.
3. The Nihilist Consumed by Hate (Post-Itachi)
The most extreme breaking point in his psychology occurs when he discovers the truth about Itachi's sacrifice and the manipulation of the Leaf Village (Konoha).
Emotional instability: His pain transforms into blind fury. The tactical coldness that characterized him disappears and gives way to a deranged laugh and genuine sadism.
Ruthless cruelty: At this stage, he no longer cares about anything. He is willing to sacrifice his own allies (like Karin), and his goal changes radically: he no longer wants to kill just one man; he wants to completely destroy Konoha and erase its ninja system. He becomes completely psychopathic and antisocial.
