Light Yagami's actions within Death Note have a significant impact on the broader societal structures and institutions. His use of the Death Note to eliminate criminals initially brings about a sense of justice and safety in society as crime rates drop. However, as he becomes more power-hungry and manipulative, his actions lead to a breakdown of trust in institutions like the police and justice system. The emergence of Kira as a vigilante figure challenges the existing power dynamics and moral values within society, leading to chaos and fear among the general population. Ultimately, Light's actions highlight the fragility of social structures and the consequences of unchecked power on societal norms.
