Ethics play a complex role in Light Yagami's decisions in the anime "Death Note." At the beginning of the series, Light initially justifies his actions by believing he is creating a better world by eliminating criminals. However, as the series progresses, his sense of ethics becomes increasingly distorted as he becomes more power-hungry and manipulative, blurring the lines between right and wrong. Ultimately, Light's actions demonstrate a moral decline as he justifies increasingly unethical decisions in pursuit of his own vision of justice.
