In Death Note, the theme of the danger of absolute power is portrayed through the character Light Yagami's descent into megalomania and corruption after obtaining the Death Note, a supernatural notebook that allows him to kill anyone by simply writing their name in it. As Light gains the ability to dictate who lives and dies, he becomes consumed by his own sense of righteousness and starts to believe he is a god-like figure with the right to pass judgment on others. This thirst for power ultimately leads to disastrous consequences, showcasing how unchecked power can corrupt even the most well-intentioned individuals.
