In the anime Death Note, the concept of justice is portrayed as subjective through the main characters Light Yagami and L. Light believes that he is delivering justice by using the Death Note to eliminate criminals, while L, on the other hand, believes in upholding the law through due process and investigation. This difference in their perspectives highlights how justice can be interpreted differently by individuals based on their own beliefs and values. The show challenges viewers to question what true justice means and whether the ends justify the means.
