King's genius here isn't simply cataloguing moral failures—it's showing how each vice masquerades as practical wisdom. Cowardice doesn't announce itself; it whispers about prudence and self-preservation. What makes this structure remarkable is that the first three questions *feel* reasonable until conscience arrives and exposes them as narrow. A person might refuse to speak up about discrimination at work because it's "safer for my family," unaware they've mistaken self-protection for principle—and King's framework lets them see the substitution clearly.
