Killer Batman

TIM BURTON MOVIES

Tim Burton's movies are the only Batman movies which depict Batman as a cold blooded killer. In Batman, he remotely dropped a bomb in Axis Chemicals factory in front of Joker's goons, largely decimating their numbers,

 

He guns more of them down with a machine gun

 

and soon after, he dropped one of Joker's goons into his death

In Batman Returns, he calmly sets one of the members of the Red Triangle gang on fire with cold blood

And soon after straps a bomb to another one

Keaton's Batman could be quite cruel, killing – or, in the case of the Fire Breather, maiming – a few henchmen in Burton's two films. Later, he straps a bomb to a tattooed strongman, which explodes and kills him. – IGN

Daniel Waters: We live in dark times. You can't just drop bad guys off in a spider web in front of city hall.

This portrayal harks back to Batman's original template. Batman used deadly weapons and didn't think twice about killing his enemies and criminals.

Batman was a killer from his very first appearance in Detective Comics # 27 in which can see him dropping a criminal into the vat of acid saying "A fitting ending to his kind". That , of course, wasn't his only kill in this issue

He was a grim figure in his first years, casually killing criminals, and Bob Kane liked this dark version best (Batman: The Complete History).

He used guns to take out his enemies (panel below from Detective Comics #32)

But also used other means, like for example ropes (panel below from Batman #1)

 

Or his own strength (panel below from Detective Comics #30)

And acrobatic skills , the same way as he did in the 1989 movie (panel below from Batman #4)

There is a common misconception that the reason why the early Batman killed and used guns is because he wasn't given his origins yet. This misconception is that once Batman was given his origins he hated fire weapons and vouch not to kill. That is very far from the truth. In the very same issue in which Batman is given the origins  (Detective Comics #33), he uses a gun and is also portrayed in the last panel with a smoking pistol.

 

Furthermore, very soon after, in Batman #1, he is even more vicious than in his first appearance, carrying a sidearm and using a machine gun to gun down his enemies (he did the same in the 1989 movie) - a group of men who were given growth hormones by Hugo Strange (panel below from Batman #1)

The real reason why Batman stopped killing in the comic books (the sudden change was not explained in-universe) was that the editor, Whitney Ellsworth, "decreed that in the future Batman would be forbidden to use a gun or kill anyone by other means. This ban was the first step in forming an ethical code that would stand DC in good stead "(Batman: The Complete History). 

Bob Kane: In the first year Batman was a grim vigilante who operated outside of law. (Batman and Me book)

Bill Finger: I was called on the carpet by Whit Ellsworth. (...) The editors thought that making Batman a murderer would taint his character, and mothers would object to letting their kids see and read about shootings. The new editorial policy was to get away from Batman's vigiliantism and to bring him over to the side of the law. We made him an honorary member of the police force.(Batman and Me book)

The in-universe debut of Batman's vow for no killing rule and the hate for firearms (caused by his parent's deaths) appeared as late as 1988 in Detective Comics #583 where the oath is mentioned. 

Although a no-kill moral code has been mentioned before

In 2004's The Forensic Files of Batman he can be seen taking the vow. There Bruce, while doing this research, creates a sense of principles for himself. Since a gun took away his parents, he plans never to use a firearm. And since he felt the effect of death at such an early age, he vows never to take a life. He does however, mention that he doesn't kill several times since the 80's

While Batman stopped killing for a long time (he was killing again, although occasionally ever since the late 60's), he never showed any kind of exceptional resentment or fear towards fire weapons and there's far too many examples throughout the decades to present them all, but he did use them during every age. The Golden Age:

Detective Comics #33

Silver age (panel below from World's Finest Comics #27)

In the 60's (Panel below from Detective Comics #327)

In the 80's (Panel below from Batman Year Two)

and 90's (panel below from Detective Comics #627)

And still uses them occasionally today (panel below from Detective Comics #710)

In the 90's however, it was established even clearer that Bruce/Batman hates guns 

And while Batman stopped killing ever since the 1943 due to becoming a kid friendly character, despite the fact that he got his moral code he resumed occasional killing starting with the late 1960's in Brave and The Bold # 83 in which he destroys a German plane using a hand grenade and uses dynamite to blow up a convoy of German soldiers as they are crossing a bridge. As Batman said while breaking his rule in Batman #420 (1988): Sometimes you have to ignore the rules. I'm not in this business to protect the rules, I serve justice. Since there's also too many instances showing Batman occasionally killing since the late 60's, here are just a few more examples from each decade

Batman #420. He traps KGBeast and leaves him to starve, while contemplating on breaking the rules

Detective Comics #590 (accidental)

In the 90's

Detective Comics #613 -  accidental

In 'Family' (Legends of the Dark Knight #31, June 1992) Batman travels to the Corto Maltese to rescue Alfred from a South American racketeer named El Vato. As they are escaping El Vato's base, Alfred runs down a pair of soldiers using a stolen lorry. Batman then triggers some explosives he'd planted in a weapons depot, blowing the villains' base to smithereens and killing many of El Vato's men in the process. This was clearly a calculated and premeditated act. Right at the beginning of the comic Batman had thought to himself: "I want to kill them [...] God help me, Alfred. I may just kill tonight. If that's what it takes to save you." And indeed he did.

Legends of the Dark Knight #84 - Batman tries several times to kill the villain, a hallucinating soldier who's been driven kill crazy by military experiments. He finally succeeds in killing the solider by shooting him several times with a handgun and knocking him off a dam

In 2000's  

Batman #576

All Star Batman & Robin the Boy Wonder #1

Detective Comics #814

Detective Comics #821

Batman #673. Forces Chill to kill himself

Batman/Doc Savage #1

In Year One: Batman/Ra's al Ghul (2005) Batman intentionally kills two bad guys who are pursuing him on snowmobiles by firing a flaregun at a mountain and creating an avalanche that buries them.

Although the modern age Batman kills mostly for self defense,

that's not always the case, as also illustrated by some panels above. When the enemy seems to dangerous to be kept alive, Batman does what's necessary. Some examples:

  

Batman #271 (1976)

 Batman #337 (1981)

In Batman: Legends of the Dark Knight # 54, a demon called Osric Drood gains power by draining Batman's blood, and as he explains, he can only sustain his energy using murderers' blood. By the end of the story Bruce wonders if he would save the man he had killed in self defense if he had a chance

JOEL SCHUMACHER MOVIES 

 Throughout Batman Forever Batman keeps talking about how killing criminals is wrong and is trying to pass that view on to Robin. At the end he throws coins at Two-Face causing him to lose balance and fall to his death. 

However, taking into consideration the running anti-killing theme in the movie and what Batman is teaching Robin, it's most likely that this death was accidental and Batman just wanted to distract Two Face. Since he barely caught Chase and Robin despite being ready for it and jumping in immediately after them, there was no chance in saving Two-Face once he tripped.

VAL KILMER'S KILL COUNT: 1

GEORGE CLOONEY'S KILL COUNT: 0 

 .........................................................

CHRISTOPHER NOLAN MOVIES 

Christopher Nolan's movies present a Batman whose moral code is as strong as in Joel Schumacher's Batman movies. 

In Batman Begins, the explosive chain reaction that Bruce started caused many deaths (8 onscreen) but they most likely weren't intended. Bruce wanted to have a distraction to escape and weaken the League of Shadow ninjas, but the fire caused more than he counted on.

By the end of the movie Batman lets Ra's Al Ghul die by leaving him in a racing train whose controls has been disabled 

In The Dark Knight Batman saves Joker from certain death but soon after kills Two-Face by throwing him and himself off the ledge. 

This is apparently an unplanned kill as well. Two-Face was standing close to the edge and Batman jumped at him trying to stop him from killing Gordon's son. He only had one hand to hold on and one to grab the boy

Jonathan Nolan: He has this one rule, as the Joker says in The Dark Knight. But he does wind up breaking it. 

Christopher Nolan: He breaks it

David Goyer: In the first two

(The Dark Knight Trilogy: The Complete Screenplays)

CHRISTIAN BALE'S KILL COUNT: 10
