Should Batman kill the Joker? The answer reveals everything about how we think about morality.

The Joker has killed thousands. Batman could stop him permanently — but won't. Is that moral courage or moral failure? And what does a comic book superhero have to do with the most important debates in ethical philosophy?

More than you might think.

In this episode of Good Is In The Details, hosts Gwendolyn Dolske, Rudy Salo and guest co-host Konstantin Hatcher sit down with philosopher and author Mark D. White to dig into his book Batman and Ethics (Wiley Blackwell) — a rigorous, accessible examination of the Dark Knight's moral code through the lens of Western ethical theory.

What we explore in this episode:

• Why Batman's refusal to kill the Joker is one of the most compelling case studies in deontological ethics in popular culture
• How Batman's overall mission — sworn to protect Gotham from crime — is essentially utilitarian, asking us whether his actions produce the greatest good for the greatest number.
• How Batman's actions and words reveal a deeply conflicted hero whose moral behavior reflects a mix of utilitarianism and deontology — demonstrating the value of each while showing how difficult it is to pursue them simultaneously.
• The trolley problem, Batman-style: if you could save hundreds of lives by taking one, are you morally obligated to do it?
• Whether Batman's refusal to kill the Joker — rooted in the deontological conviction that killing is wrong regardless of consequences — is really about moral integrity, or whether it puts his own virtue above the lives he could save.
• What virtue ethics adds to the conversation — and why Batman's character matters as much as his rules
• The ethics of vigilantism, torture in pursuit of justice, and what it means to operate outside the law in service of a higher moral mission.
• Is Batman actually happy? What Aristotelian eudaimonia — flourishing and the good life — looks like for a man who has dedicated his existence to fighting crime

This is public philosophy at its most engaging: real ethical frameworks — utilitarianism, deontology, virtue ethics — made vivid and debatable through one of the most iconic characters in fiction. Whether you're a philosophy student trying to understand Kant and Mill, a comics fan who has always wondered about Batman's "One Rule," or simply someone who wants to think more clearly about right and wrong, this episode is for you.
