In Haruki Murakami's "Dance Dance Dance," a pessimistic view on human nature emerges through the phrase "Can't trust people. Won't do any good." This reflects a deep-seated belief that trust is futile because people are often driven by self-interest and betrayal. The assertion extends to the notion that individuals will harm not only others but ultimately themselves, creating a cycle of destruction and hopelessness.

This perspective resonates throughout the book, highlighting a world where human connections are frail, and individuals struggle with their inner demons. Murakami's exploration of these themes invites reflection on the complexities of trust, relationships, and the inherent darkness in human behavior.
