Personality Sukuna is selfish, heartless, amoral, and an outright sadist. After reincarnating shortly after Yuji Itadori swallowed his finger, he expressed a desire to kill women and children, likening them to crawling larvae. Due to his immense strength, he rarely concerns himself with the consequences of his actions, even if they affect his vessel, Yuji Itadori. In fact, he often mocks and insults Yuji, calling him a scoundrel, and even laughed and enjoyed his despair on multiple occasions.
