Light Yagami and L, two main characters in the anime series Death Note, have contrasting views on justice. Light Yagami believes in his own form of justice, where he sees himself as a god-like figure who punishes criminals by killing them with the Death Note. He believes that he is creating a better world by eliminating all those he deems unworthy.
On the other hand, L, a brilliant detective, believes in upholding the law and using his intelligence and skill to catch criminals through legal means. He values due process and the legal system, aiming to bring justice through lawful investigation and capture of wrongdoers.
In summary, Light Yagami's concept of justice revolves around his personal sense of morality and power to enforce it, while L's concept of justice is grounded in the rule of law and ethical principles.
