Light Yagami, the main character in the anime "Death Note," initially sees his actions as serving justice and creating a better world by eliminating criminals. However, as he continues to use the Death Note to kill those he deems unworthy, he becomes increasingly consumed by power and the consequences of his actions.
As the Death Note brings him closer to achieving his goal of becoming the "god of the new world," Light's psychological state deteriorates. He becomes more isolated, paranoid, and detached from those around him. The toll of his actions weighs heavily on him, but he rationalizes his behavior by convincing himself that the end justifies the means.
Ultimately, Light's inability to cope with the emotional and psychological burden of his actions leads to his downfall. His arrogance and god complex blind him to the impact his choices have on himself and those he cares about, leading to his eventual demise.
