Light Yagami's actions in the anime "Death Note" ultimately lead to a significant transformation in his sense of righteousness. Initially, he believes he is a righteous vigilante seeking to rid the world of criminals and create a utopia. However, as he becomes consumed by power and the Death Note, his actions become increasingly ruthless and morally ambiguous. This gradual descent into darkness challenges his original beliefs and sense of righteousness, ultimately leading to a deep internal conflict and moral degradation.
