Light Yagami, the main character in the anime "Death Note," often rationalizes his actions as necessary for achieving his goal of creating a utopian society free from crime and corruption. He believes that by using the Death Note to eliminate criminals and those he deems unworthy, he can bring about a better world where people can live without fear. Light sees himself as a vigilante or savior, willing to make the tough decisions and sacrifices in the name of justice. His strong sense of righteousness and belief in his own moral superiority drive his actions and help him justify the extreme measures he takes.
