Light Yagami, the main character in the manga and anime series "Death Note," initially views himself as a "god" or "savior" who is bringing justice to the world by using the Death Note to eliminate criminals. He believes that his actions, though extreme, are ultimately for the greater good of society. Light believes that he is on the side of good, seeing himself as a hero and justifying his actions as necessary for creating a utopia free from crime and corruption. However, as the series progresses, his perception of good and evil becomes more complex and ambiguous, leading to moral dilemmas and self-reflection about the consequences of his actions.
