The rules of the Death Note create ethical dilemmas for its users by forcing them to make decisions about who deserves to live and who deserves to die. Users must grapple with the moral implications of playing god and taking the lives of others, even if they believe they are doing so for a just cause. Additionally, the rules of the Death Note limit the user's ability to control the outcomes of their actions, leading to unintended consequences and moral dilemmas.
