I'm NOT SAYING HE NEEDS HIM TO BE THE PUNISHER.
I'm telling you cats WHY the dynamic works in the comic. and why it wont work in the film if superman is a stone cold killer.
Batman skirts the law, while Superman is by the book.
Superman is "We do things by the book"
Batman is "fukk that, this is how things have to be"
What I said about Batman being Punisher is, Batman can kill, he's not the threat superman is.
But once you make superman a killer, you literally have to put him at the Top of Worlds Most Wanted, He is a god, without a sense of morality.
Batman can't kill that's the point. He can make threats to kill but he wouldn't. Again, let's see batman v superman and then we can go back to this discussion. Let's try letting characters evolve and see where the story goes
