Light Yagami, the main character in the anime "Death Note," initially believes that he is justified in using the Death Note to rid the world of criminals and create a utopia. He sees himself as a hero and as the savior of humanity. However, as the series progresses, Light's ego and desire for power lead him to become more ruthless and willing to sacrifice innocent lives to achieve his goals. Despite the moral ambiguity of his actions, Light justifies his choices by believing that the end justifies the means. Ultimately, Light's ambition and lack of empathy for others showcase how he becomes consumed by his own sense of justice, blurring the lines between right and wrong.
