Everybody knows that Batman has one rule. It's a rule as old as the Pyramids, as old as time, as old as Cher.
OK, so it's not that old, but it's as old as Bruce Wayne. And sure, there have been rare exceptions in the comics - but generally speaking, and always in the movies, Batman does not kill.
Which makes this new tease from Charles Rovan, talking to Empire Magazine, really quite thrilling...
[Batman] is not giving people a chance… He is more than a vigilante. He has become not only the cop, if you will, he has also become the jury and executioner.
Wait, what? "Jury and executioner"? Unless Rovan is talking metaphorically, that sounds an awful lot like we'll be seeing Batman go for blood in Batman vs Superman.
He already looks pretty mad in this TV spot released at the weekend...
...but I think it's safe to say it won't be Superman whose blood ends up on Bruce's hands. In Batman Begins, he did leave Ra's al Ghul to die on the subway train, but it wasn't a direct kill.
Clearly, DC are establishing a grittier world for Batman to exist in with their new cinematic universe and the birth of the Justice League. The question now is:
Can Batman still be a good guy if he literally becomes an executioner?
We'll get our answers on March 25th. Check out the full trailer for Batman vs Superman below.
