The manipulation of fate and circumstances plays a central role in Light Yagami's plans and schemes in the anime "Death Note." Light believes that by using the Death Note to control the fate of others, he can create a better world by eliminating criminals and establishing himself as a god-like figure of justice. This manipulation reflects Light's belief in his own superiority and his extreme sense of righteousness, leading him to justify any means necessary to achieve his desired ends. Light's worldview is shaped by his belief that he alone has the power and intelligence to bring about a utopia, even if it means manipulating fate and circumstances to do so.
