Just following your logic, what with those trying to leave? A random worker thinking "ok, I've saved enough to move out my county" and Boom, a bomb fall. What would you say? "Sorry pal, move faster nex time"?
I think you talk because is free, just fiat rethoric. Anyone who thinks through what you propose would at least be hesitant on celebrating someone else's dead.
Don't think for a second you're moral standards are suoerior just for asking "can someone kill the bad guys please"
