In "Death Note," the main character Light Yagami gains the power to kill anyone by writing their name in a supernatural notebook, the Death Note. This power allows him to act with impunity, as there are initially no consequences for his actions. As the story unfolds, "Death Note" examines how the absence of immediate consequences affects Light's moral compass and his belief in his own righteousness. It delves into questions of morality, ethics, and the consequences of absolute power, ultimately showing how even in a world seemingly without consequences, moral decisions still have repercussions on both a personal and societal level.
