Light Yagami, the protagonist of the manga and anime series "Death Note," initially rationalizes his use of the Death Note as a tool to create a utopia by eliminating criminals and evildoers. He believes that by doing so, he is bringing justice to the world. As the series progresses, Light becomes more consumed by power and his own ego, leading him to justify increasingly questionable and immoral actions in the name of his vision of justice. Ultimately, Light's moral compass becomes heavily skewed as he becomes willing to sacrifice innocent lives to maintain his facade and achieve his goals.
