Light Yagami, the main character in the anime "Death Note," rationalizes the deaths caused by the Death Note by believing that he is using the power of the Death Note to create a better world. He sees himself as a "god" who is purging the world of criminals and wrongdoers, believing that the end justifies the means. Light convinces himself that the sacrifices he makes are necessary for the greater good and to create a utopia where crime is eradicated.
