In "Death Note," the theme of control is primarily explored through the character Light Yagami's use of the Death Note to exert power over others by controlling their fates through the notebook's ability to cause death. This control over life and death allows Light to manipulate and eliminate those he deems as obstacles in his pursuit of creating a utopian world under his control. The series also delves into the consequences and ethical dilemmas that arise when one individual holds such immense power and control over others, ultimately questioning the nature of control and the limits of human authority.
