In Joseph Heller's "Catch-22," the character's reflection on racial prejudice highlights the deep moral failing in how people treat others based on their race or ethnicity. The quote emphasizes that it is profoundly wrong to demean an honorable individual by using derogatory terms associated with various minority groups. This condemnation of racial slurs signifies a broader critique of societal attitudes toward race and the injustices faced by marginalized communities.

The message underscores the importance of recognizing the humanity of all individuals, regardless of their background. Heller’s work not only addresses the absurdities of war but also delves into the prejudices that can persist within society. By framing racial prejudice as a "terrible thing," the author calls for empathy and respect towards others, urging a reevaluation of how we address differences among people.
