The rules of the Death Note create moral ambiguity for its users by posing ethical dilemmas related to the use of the notebook. Users are faced with decisions about who deserves to die, the consequences of their actions, and the impact on their own morality. The rules, such as the limitations on the number of characters in the victim's name or the cause of death, force users to consider the implications of their choices and the ethical boundaries they are willing to cross. This moral complexity adds layers to the story and challenges viewers to reflect on the nature of justice and the consequences of wielding such power.
