In "Death Note," the consequences of using justice as a weapon are depicted through the main character, Light Yagami, who obtains a notebook that allows him to kill anyone by writing their name in it. As Light takes on the persona of "Kira" and uses the Death Note to eliminate those he deems as criminals, he believes he is bringing about a sense of justice and a better world. However, the series also shows the dark and destructive consequences of his actions, as he becomes consumed by power, loses his sense of morality, and faces severe repercussions for his choices. This portrayal highlights the complexity and moral ambiguity of using extreme measures in the name of justice.
