Demonstration
The distinction between restraint and weakness becomes central to his renewed authority.
Public Casualties

Responsibility
Batman answers by pursuing protection and containment rather than allowing outrage to dictate his action.

Refusal
Batman’s final resistance preserves a moral difference even as the confrontation approaches mutual destruction.
Principle Continued

Principle Continued
