Addressing Murderous Batman

In addition to the confusing Knightmare scene, Justice League was supposed to address Batman’s murderous nature. The film explained it, but some fans were just not satisfied.

The scene in which Wonder Woman pops Bruce Wayne's shoulder went differently before the reshoots. The exchange was supposed to reference Wayne’s guilt over killing others, along with his feeling that such guilt can only be washed away through his own sacrifice.

It does sound a bit cheesy and illogical. But it explains Batman's out-of-character, completely unnecessary, and totally illogical plan to break the shield surrounding Steppenwolf's base and attract all of the Parademons.
