Ethical Problems of Enforcing Justice in Death Note and Psycho-Pass Anime

What happens when justice is controlled by a single person or a powerful system? This research explores how Death Note and Psycho-Pass show the dangers of extreme justice. In Death Note, Light Yagami takes the law into his own hands, believing he can create a perfect world by eliminating criminals. In Psycho-Pass, an advanced AI system judges people before they even commit crimes, deciding their fate based on predictions. Both systems aim to reduce crime but end up threatening personal freedom and fairness. By comparing these stories, this study highlights the risks of justice without balance, questioning how much control should be given to authority.
