Nobody Does Evil on Purpose. Really?

This episode examines the Stoic claim that nobody does wrong on purpose — that all evil acts arise from mistaken judgment about what is good. It tests this idea against ancient contradictions, including Medea, and modern findings on psychopathy and compulsive behavior. The host then highlights a practical takeaway: catching the brief moment of assent before it hardens into action, which remains a valuable self-mastery tool.

Canon

•
No One Does Evil on Purpose
The Stoics argue that all wrongdoing stems from ignorance: people always choose what they believe is good, and if they choose evil, it's because they misjudge what is truly good.

Highlights

•
Catch the Assent Before Action
The practical lesson is to catch the 'assent'—the fleeting moment between an impression and the impulse to act—and to withhold agreement, thereby breaking the chain that leads to harmful behavior.

Editorial

•
Psychopathy Challenges the Ignorance Model
Modern psychopathy research suggests that some individuals can recognize something as wrong and still commit it without remorse, challenging the Stoic premise that all wrongdoing comes from ignorance.
