Sukuna is a sadistic, cold-hearted entity, reveling in chaos and despair. Immensely powerful and arrogant, he views humans as insignificant, likening them to insects. Lacking empathy and disdaining the weak, his worldview aligns with social Darwinism. He's highly intelligent and manipulative, but dismissive of others, unable to comprehend love or the value of relationships. His personality is marked by selfishness, cruelty, and a nihilistic disregard for life.
