Light Yagami, the protagonist of the anime and manga series "Death Note," initially believes that his actions are justified in the name of creating a better world by eliminating criminals. He rationalizes his actions by convincing himself that he is serving justice and purging society of evil. However, as the series progresses, Light becomes increasingly consumed by his power and the consequences of his actions. He starts justifying more extreme measures and becomes more ruthless in maintaining his control. Ultimately, Light's inability to confront the moral and ethical implications of his actions leads to his downfall.
