Batman / Batman Joker

Did Batman Ever Kill the Joker?

The relationship between Batman and the Joker is one of the most iconic rivalries in comic book history. The Clown Prince of Crime has caused chaos and destruction throughout Gotham City, constantly pushing Batman to his limits.

Many fans have wondered if there was ever a point where Batman crossed the line and killed the Joker. Let’s explore this topic further.

Batman’s No-Killing Rule

Batman’s strict code of ethics prohibits him from killing anyone, even his arch-nemesis, the Joker. This code is an essential part of the character’s moral compass, and he believes that taking a life would make him no better than those he fights against.

Instances Where Batman Almost Killed the Joker

There have been multiple instances in comic book history where Batman was pushed to his breaking point by the Joker’s actions. In “The Killing Joke,” the Joker shoots and paralyzes Barbara Gordon (aka Batgirl), which leads to her adopting the identity of Oracle. In response, Batman comes close to killing the Joker but ultimately chooses not to, stating that it would be too easy.

In “A Death in the Family,” readers were given a chance to vote on whether or not Jason Todd (the second Robin) should live or die. The majority voted for Jason Todd to be killed off, and it was revealed that the Joker was responsible for his death. Batman later confronts him but ultimately decides not to kill him.

Alternate Reality

In some alternate reality stories such as “Injustice: Gods Among Us,” a darker version of Superman kills the Joker after he tricks him into killing Lois Lane and their unborn child. This act sets off a chain reaction that leads to Superman becoming a tyrant ruling over Earth with an iron fist.


To answer the question, no, Batman has never killed the Joker in the main continuity of comic book history. Batman’s no-killing rule is a fundamental aspect of his character, and it’s highly unlikely that he would ever break it.

However, there have been instances where he has come close to killing the Joker but ultimately chooses not to. The dynamic between the two characters is what makes their rivalry so compelling, and it’s unlikely that we’ll ever see an end to it.
