Re: They are going ahead with a Justice League movie
Yeah, Batman's "no killing" rule is... "Oddly" treated in the movies. Especially in "Begins" where he tells Ras "I'm not going to kill you, but I don't have to save you."
Um... Yes, you do, Batman. That's sort-of what a hero who "doesn't kill" does!
By that logic everyone is a killer at all times no matter what they do.
You get hurt, hurt 'em back. You get killed, walk it off.
