Light Yagami's actions in Death Note have a significant impact on societal structures and institutions within the series. He starts off as a high school student who gains the power to kill anyone by knowing their name and face. Light uses this power to eliminate criminals, which initially leads to a decrease in crime rates and increases public safety. However, as Light becomes more power-hungry and uses the Death Note to further his own agenda, he manipulates and undermines societal structures, such as law enforcement and justice systems. His actions blur the lines between right and wrong, leading to a breakdown in traditional moral and ethical values within the society portrayed in Death Note. Ultimately, Light's actions result in chaos and distrust among the population as he attempts to establish himself as a god-like figure through his manipulation of the Death Note.
