In Death Note, the main character, Light Yagami, originally seeks to use the Death Note to rid the world of criminals and create a utopia. However, as he becomes more obsessed with power and control, his noble goal becomes corrupted by his own desire for dominance and fear of losing his newfound authority. This transformation showcases how noble ideals can be twisted and perverted when driven by selfish motivations, ultimately leading to the downfall of the protagonist.
