Light Yagami's actions in the series "Death Note" have a significant impact on his sense of morality and righteousness. At the beginning of the series, Light believes that he is morally justified in using the Death Note to rid the world of criminals and create a utopia. However, as he continues to use the Death Note and becomes more power-hungry, his sense of morality becomes increasingly skewed. He starts to see himself as a god-like figure with the authority to judge and punish others, leading him to justify increasingly immoral actions in the name of his own sense of righteousness. Ultimately, Light's actions lead him down a path of moral decay and corruption, causing him to lose touch with his original sense of right and wrong.
