Light Yagami, the protagonist in the anime series "Death Note," initially believes that his actions are justified in his quest to create a better world by using the Death Note to eliminate criminals. However, as he continues to use the Death Note and faces opposition from others, he begins to show signs of mental and emotional strain.
At first, Light remains confident and rationalize his actions as necessary for the greater good. However, as he faces challenges from the detective L and others who try to stop him, Light's behavior becomes increasingly erratic and his mental state begins to deteriorate. He becomes more paranoid and isolated, leading to a sense of alienation from those around him.
As the death toll rises and Light's actions are exposed to the public, he struggles with guilt and inner conflict. His once strong sense of justice becomes corrupted, and he becomes consumed by the power of the Death Note. This ultimately leads to his downfall as he is unable to cope with the psychological and emotional toll of his actions.
In summary, Light Yagami handles the psychological and emotional toll of his actions by initially rationalizing them, but ultimately succumbs to the overwhelming guilt and inner turmoil brought on by his quest for power and control.
