The quote reflects a profound sense of existential questioning faced by the character. It suggests a struggle between personal self-doubt and the perception of societal issues. This tension forces the character to confront the possibility that if he is not at fault, then the larger world around him holds flaws that make life seem pointless.
Additionally, the character grapples with the fear of living a life without purpose. The idea that a world devoid of problems might render his existence meaningless adds to the weight of his contemplation. This resonates with a common human anxiety about the value and direction of one's life in the face of external realities.
