Light Yagami's pursuit of justice in the anime "Death Note" ultimately leads him down a dark path of moral ambiguity and obsession with power. As he becomes consumed by the idea of being a "god" of justice, his mental and emotional well-being deteriorates significantly. His intense focus on achieving his version of justice results in paranoia, isolation, and a loss of empathy towards others. This obsessive quest for power and control takes a toll on his psyche, leading to a decline in his mental health and emotional stability.
