Cut the crap. We are all part of a single society - people of the earth. Follow your logic we should be doing nothing else but trying to stop the world acting the way it does. The atrocities are everywhere. I would not be able to sleep and function at all if I've felt that "collective" responsibility. This is not how humans work.
