If they actually do kill off Batman/bruce in this I'm going to be ROYALLY pissed.
Why? Either way, this is the end of this version of the character on screen.
It's just a no-no.
He's an immortal character of pop fiction that hasn't died on screen cause he's a symbol of the fight you wish you could fight. To attain the justice you feel at times might be otherwise denied. To kill him would be to say that justice fails. That hope isn't worth having.
Even the on screen Superman Returns death was a fake out.
You don't kill James Bond.
You don't kill Batman.
