Light Yagami, the main character in the anime "Death Note," initially believes he is doing the world a service by using the Death Note to eliminate criminals and create a utopia. He rationalizes his actions by convincing himself that he is purging the world of evil. However, as the series progresses, Light's moral compass becomes increasingly skewed as he becomes more power-hungry and begins to justify killing innocent people to achieve his goals. Ultimately, Light's descent into darkness and his struggle with the moral complexities of his actions lead to his downfall.
