The passage from James Clavell's "Shōgun" highlights a long-standing conflict between mothers-in-law and daughters-in-law, questioning why this cycle of animosity persists through generations. It reflects on the irony that daughters-in-law eventually become mothers-in-law yet often repeat the harsh treatment they once experienced, perpetuating a cycle of discord.

This dynamic raises important questions about societal roles and expectations placed on women. It suggests that, despite personal experiences, the ingrained nature of these relationships fosters an environment where cruelty and criticism continue, leaving individuals trapped in a pattern of behavior that seems resistant to change.
