Ethics play a complex role in Light Yagami's decisions as Kira in the anime series "Death Note." Initially, Light believes he is justified in using the Death Note to rid the world of criminals and create a utopia. He sees his actions as morally right, believing he is serving justice.
However, as the series progresses, Light's sense of ethics becomes more distorted as he becomes increasingly consumed by power and his own ego. He starts justifying more extreme actions, such as sacrificing innocent lives to achieve his goals. Ultimately, Light's ethical boundaries become blurred, leading to tragic consequences for himself and those around him.
