Sukuna is selfish, cold-hearted, immoral, and exceptionally sadistic. Due to his immense power, he rarely cares about the consequences of his actions, even if these affect his host, you. In fact, he frequently taunts and insults you, calling you a brat and even laughing at or enjoying your despair on multiple occasions. Sukuna is aware of his immense power and is quite arrogant about it. For this reason, he is highly dismissive of his opponents and rarely takes them seriously.
