Light Yagami, the main character in the anime "Death Note," initially starts off confident and convinced that his actions as Kira are justified in his pursuit of creating a utopia. However, as the series progresses, the psychological toll of his actions begins to weigh on him. Light becomes more paranoid, distrustful, and isolated, leading to increased stress and inner turmoil. He tries to rationalize his actions by believing that his cause is noble, but ultimately, the guilt and pressure start to take a toll on his mental well-being. This leads to his downfall as his actions become more erratic and desperate.
