The Joker isn’t involved in Elixir’s nefarious business, but Batman’s description of Ambrose’s aberrant methods perfectly explains why the Joker is Batman’s archnemesis despite his lack of superpowers.

Batman’s rogues may be particularly dreadful in comparison to other heroes' foes, but most of Gotham’s A-list criminals have at least one weak spot.Physically monstrous villains like Killer Crocand Clayface cherish the humanity beneath their power, pragmatic criminals like the Penguin and Mister Freeze have their own set of morals, and twisted minds like the Riddler and Scarecrow sometimes recover their judgment and retire.

Meanwhile,the Joker is the personification of pure chaos. He often plays his cards in a way that helps him gain power in Gotham, or he adds social commentary to his attacks. However, the Joker’s goals are almost always centered exclusively on causing as much damage as possible, and he doesn’t care how many innocent people need to die in the process. The Joker is eager to betray his allies and increase the casualty count just to spite Batman.

The Joker’s Lack Of Empathy Is The Perfect Challenge For Batman’s No-Kill Rule

Batman & The Joker Are Trapped In An Unbreakable Cycle

The Joker is incapable of remorse or rehabilitation. No prison holds him for long, no treatment changes him, and no level of containment fully prevents his chaos. Batman knows this, but he continues to adhere to his no-kill code. As a result,Batman and the Joker are locked in an unbreakable cycle where the Joker constantly escalates his violence and Batman frustrates the Joker’s attempts to pull him down into bloodthirst.

Ruthless enemies like Elixir’s Ambrose exhibit the same dangerous characteristics as the Joker, though Batman usually finds creative ways to neutralize them. With the Joker, these options never truly exist. No gadget, strategy, or long-term plan preventsthe Joker’s return. The bestBatmancan do is minimize the casualties and brace for the next round.
