I think I would feel the same way as the people in the restaurant, Macha.
If the Pakistani military (for example, or any other nation's military) bombed my families house and killed my familiy, even by accident, I would probably hold hatred, or at least the urge for revenge.
How I would enact revenge, if at all, I don't know.
I'd probably target someone in the military, or their family.
(Right now this is hypothetical of course.)
