Should Batman Kill the Joker? (3)



It would have been so easy for the Batman to kill the Joker. Batman is an expert exponent of many types of martial arts.

The philosophical system of utilitarianism will have not problem with Batman killing the Joker to prevent Joker from committing further crimes. As we have seen from our earlier posts about the trolley and the surgeon, it is not as straight forward as it seems.

In the Hush storyline, Hush asked the Batman, "How many lives do you think you've cost, how many families have you ruined, by allowing the Joker to live?...And why? Because of your duty? Your sense of justice?"

In utilitarianism, the end justifies the means. A popular proponent of utilitarianism is Peter Singer, professor of Philosophy in Princeton University and in the University of Melbourne.

However, there is another system of philosophy named deontology (nothing to do with dentists) in which the act is more important. When you decide "do not kill", it means do not kill under any circumstances, irrespective of whatever good that killing may produce. Deontology is based on a sense of duty and the most well known proponent is Immanuel Kant. Of course, Immanuel Kant have never met the Joker.

"Is Batty a secret deontologist?" muses the Joker.

"I want my lawyer! Oh, that's right, I killed him too" (from The Dark Knight)
