Light Yagami, the main character in the anime "Death Note," initially believes he is justified in using the Death Note to rid the world of criminals and create a utopia. He rationalizes his actions by convincing himself that he is serving the greater good and that sacrificing a few lives is worth it for the betterment of society. However, as the series progresses, Light becomes increasingly consumed by his power and ego, leading him to make morally questionable decisions and crossing ethical boundaries in the name of achieving his goals. Ultimately, Light's descent into moral ambiguity reflects the complex and dangerous nature of playing judge, jury, and executioner.
