Light Yagami, the protagonist of the anime series "Death Note," initially justifies his actions as Kira by believing that he is creating a better world by eliminating criminals. He convinces himself that he is serving justice and bringing about a positive change. However, as the series progresses, Light's morality becomes increasingly blurred. He becomes more power-hungry and begins to manipulate and kill not only criminals but also innocent people who stand in his way. Light rationalizes his actions by deeming them necessary for his ultimate goal of creating a utopia under his rule, showing how power can corrupt one's moral compass.
