In the anime "Death Note," Light Yagami uses the Death Note to manipulate fate and control people's destinies to achieve his goal of creating a utopian world free of crime. By writing the names of criminals in the Death Note, he is able to orchestrate their deaths in a way that appears to be predetermined or fated, thereby instilling fear in the hearts of wrongdoers and gaining a sense of power and control over life and death. This manipulation of fate and destiny is a key component of Light's overall strategy to become the godlike figure he envisions himself to be.
