Light Yagami's pursuit of justice in the anime "Death Note" ultimately leads him to compromise his own sense of morality. As he becomes consumed by his quest to rid the world of criminals using the Death Note, he starts to justify increasingly questionable actions in the name of achieving his vision of a just society. This gradual descent into moral ambiguity highlights the dangerous consequences of a rigid and extreme pursuit of justice, blurring the lines between right and wrong for Light Yagami.
