In the heat of this discussion on “never kill”, it should be pointed out, at least in my view, that this is a never murder rule (be that anywhere from Murder 1-3) Is manslaughter (when one is blowing up/rolling over cars in a chase. That can be deemed as manslaughter, same for letting people be hoisted on their own petard. Leaving criminals in a build to die by the hand of their own explosive. It is murder, which has forethought, that breaks the psychological rule. As for different universes within the multiverse, we must know the specifics of his origin and psychology to make a call as to the actions of murder. Owlman, especially in his first iteration with the crime syndicate, that these are in fact doppelgangers. Only in latee versions was Owlman portrayed as Bruce’s brother and in some Bruce’s parents were never killed. In one, only his mother. One is left to wonder why DC felt compelled to make him someone different than Bruce. In the new 52, it is Alfred that killed Owlman’s parents.
If one wishes to give the character a different background and psychological trauma, than I can see where it is possible to make the character willing to commit murder. As I said, Batman’s no-kill(no-murder) rule is not based upon “morality” but trauma. Any story teller (writer, artist, director) who does not create a different psychological basis for this is merely taking a vigilante and putting them in a Bat suit. I don’t give a rats if it is Snyder, Miller, Moore, Morrison or fill_in_the_blank.
The Batman is (arguably) the most psychologically damaged of any character in comics (DC/Marvel/etc). He is the character that operates and is driven the most by his psychological damage. To ignore or not replace that damage, does the character a disservice. Also, over time, these murderous takes on Batman will be shelved in much the same way as “the rainbow Batman” and other such late 50’s-60’s versions were. History will eventually settle this debate. However, I strongly propose that The Batman will be judged in canon another 80 years from now, as having two fundamental characteristics. He doesn’t murder and he doesn’t use guns.
As for the neck snapping in The Killing Joke, I will disagree that the Batman kills The Joker, based on Jim G’s desire to have him brought in “by the book”. If anything, that moment, solidifies a rationale for Bats to not kill The Joker, even though he wants to, to honor the wishes of his friend and Bab’s father. Again, we are dealing with psychology.
We have heard from Snyder about “being real”. The biggest reality is that which drives a person psychologically.
If in fact Snyder is off to make a zombie movie, that seems only fitting. He is best suited to writing/directing mindless characters. At least he has something in common with them.
