Light Yagami's actions in the anime "Death Note" greatly affect his sense of identity and purpose. Initially, he views himself as a hero, believing he is cleansing the world of criminals and creating a utopia. However, as he continues to use the Death Note and becomes more consumed by power, his sense of morality becomes twisted, leading him to question his own identity and purpose. Ultimately, his descent into darkness and obsession with control significantly alter his perception of who he is and what his purpose truly is.
