Fear is a natural human emotion, even among those who are considered brave. The idea that someone could be fearless is unrealistic; everyone confronts fear in different situations. It serves as a reminder that courage is not the absence of fear, but the ability to move forward despite it.

In the context of a struggle or conflict, overcoming personal fear becomes one of the greatest challenges. It emphasizes that true bravery lies in confronting and managing one's fears rather than denying their existence. This concept resonates throughout Joseph Heller's "Catch-22," illustrating the complexities of human emotions in dire circumstances.
