Light Yagami, the main character in the anime series "Death Note," rationalizes his actions by believing that he is creating a new world free from criminals and wrongdoing. He sees himself as a hero who is using the Death Note to eliminate those he deems as evil, thus creating a safer and more just society. Light justifies his actions by believing that the ends justify the means, and that sacrificing some lives for the greater good will ultimately lead to a better world.
