Light Yagami's actions in Death Note have a significant impact on the broader societal structures and institutions within the series. By using the Death Note to rid the world of criminals, Light initially creates a sense of fear and uncertainty among both criminals and law-abiding citizens. However, as Light's pursuit of justice becomes increasingly corrupt and self-serving, his actions lead to the rise of a cult of personality around him, with some individuals viewing him as a savior and others as a dangerous vigilante. This ultimately results in the breakdown of traditional power structures and the erosion of trust in established institutions such as the police and judiciary. The moral and ethical dilemmas raised by Light's actions also force characters within the series to confront their own beliefs and values, leading to further societal upheaval and conflict.
