Batman / Batman Joker

Did Batman Kill Joker for Superman?

The relationship between Batman and Joker has been one of the most iconic and complex rivalries in comic book history. Their constant battles have resulted in numerous casualties, both physical and emotional.

However, in the graphic novel “Injustice: Gods Among Us,” written by Tom Taylor, we see a shocking turn of events where Batman finally decides to kill Joker. But why? Let’s explore.

The Injustice Universe

In the Injustice universe, Superman becomes a tyrannical leader after the Joker tricks him into killing Lois Lane and their unborn child. Enraged by this tragedy, Superman kills Joker in cold blood, marking a turning point for the Man of Steel. He decides that the only way to protect humanity is to control them with an iron fist.

Batman disagrees with Superman’s methods and forms a resistance group to oppose him. However, he faces a difficult decision when he learns that Superman has captured the real Joker from another dimension and brought him to their world.

The Ultimate Sacrifice

Batman knows that Joker is responsible for countless deaths and destruction. He also knows that if Superman finds out about Joker’s presence, he will kill him without hesitation. So Batman makes an unthinkable decision – he kills Joker himself.

This decision weighs heavily on Batman’s conscience as he realizes that he has crossed a line he never thought he would cross. He justifies his actions by saying that it was necessary to prevent an even greater tragedy from occurring.

However, this decision also fractures his relationship with his closest allies, including Nightwing and Batgirl, who cannot condone his actions.

The Aftermath

The repercussions of Batman’s actions are felt throughout the rest of the series. The Justice League is torn apart as heroes take sides in the conflict between Superman and Batman.

Furthermore, Batman’s decision ultimately proves futile as Superman discovers what happened to Joker anyway. This leads to a climactic battle between the two heroes, with Batman ultimately sacrificing himself to save the world from Superman’s wrath.


In conclusion, Batman’s decision to kill Joker in “Injustice: Gods Among Us” was a complex and controversial one. It showcased the lengths that Batman was willing to go to protect humanity, even if it meant compromising his own morals.

The story also serves as a cautionary tale about the dangers of unchecked power and the consequences of vigilante justice. It reminds us that even our greatest heroes are fallible and can make mistakes with far-reaching consequences.

As fans, we may never agree on whether or not Batman made the right decision, but it certainly made for an unforgettable and thought-provoking storyline.
