Light Yagami, the main character of the anime series "Death Note," initially believes that his actions are justified in his quest to create a utopia by eliminating criminals using the Death Note. However, as he continues down this path, the psychological toll begins to weigh heavily on him. He starts to exhibit signs of megalomania, paranoia, and an increasing disregard for human life.
Despite these challenges, Light Yagami remains focused on his goal and becomes more ruthless in his pursuit of justice, often justifying his actions as necessary for the greater good. He becomes increasingly isolated from those around him, including his family and friends, as he delves deeper into his role as Kira, the vigilante using the Death Note.
In the end, Light's psychological state deteriorates significantly as he faces off against his rival, L, and ultimately meets his downfall. His inability to cope with the immense psychological toll of his actions leads to his tragic demise.
