Through the cracks of justice, we see light. In his speech, Tom used the trolley problem to reveal the profound contradiction between law and human nature: when utilitarianism requires "sacrificing the minority to save the majority", the judicial system often judges legitimate defenders with strict standards, forcing victims to accurately calculate the strength of defense in critical moments, just like requiring drivers to analyze physics formulas in an instant. Through the "perfect circle" paradox, he explained that although absolute justice is unattainable, it guides the direction of civilization - from the death of Socrates to modern judicial loopholes, it is the defects that drive humans to improve their moral standards. At the end of the speech, Tom called on society to accept the imperfections of the law so that every citizen can repair the "circle" of justice.
