Light Yagami, the main character in the anime "Death Note," initially believes that his actions as Kira, the vigilante seeking to rid the world of criminals, are justified in the name of creating a better world. He rationalizes his actions by convincing himself that he is serving justice and eliminating evil from society. However, as the series progresses, Light's moral compass becomes increasingly skewed, and he becomes more willing to resort to extreme measures to achieve his goals. Ultimately, Light becomes consumed by power and loses sight of his original intentions, leading to a tragic downfall.
