Re: In hindsight what changes would you do
milost, nobody here is arguing that Bane wouldn't kill children and wasn't threatening Pavel's children.
He could have threatened Pavel's wife. Or he could have said something like "If this bomb does not go off in five months...I WILL BREAK YOUR CHILDREN."
It's the fact that he says "for the sake of your children indeed I hope it does"... that implies, "Hey I'd hate to have to do this, but you know I will, so don't make me."
