Light Yagami initially justifies his use of the Death Note as a means to rid the world of criminals and create a utopia free of wrongdoing. However, as he becomes more consumed by power and the desire to become a god-like figure, he starts to rationalize his actions by viewing himself as a necessary evil for the greater good. Over time, Light becomes increasingly detached from the moral implications of his choices, leading him to commit more heinous acts in the name of justice. Ultimately, Light's descent into darkness showcases his gradual moral decay and the dangerous consequences of wielding such power without restraint.
