In Death Note, the protagonist Light Yagami initially believes that he is using the Death Note to rid the world of criminals and create a more just society. However, as he becomes more obsessed with power and control, his noble intentions become corrupted, leading him down a dark path of manipulation, deceit, and ultimately, a complete disregard for human life. This exploration of the corruption of noble ideals is portrayed through Light's transformation from a well-intentioned individual to a power-hungry megalomaniac, highlighting the dangers of absolute power and the moral consequences of pursuing noble goals through unethical means.
