In the book "King Rat" by James Clavell, a significant message is conveyed about the importance of personal integrity and decision-making. The quote emphasizes that while there may be varying degrees of honor among individuals, each person must adhere to a singular moral code. It highlights the freedom and responsibility of individuals to make their own choices, suggesting that self-determination is paramount in navigating life's challenges.

The passage also warns of the potential consequences of poor decisions, indicating that a wrong choice at a critical moment can have more devastating effects than physical harm. This serves as a reminder to guard one's conscience diligently, as personal accountability is essential in maintaining one's values and identity in difficult circumstances.
