omelet making, "star wars"-style

Professor Bainbridge asks "Was the Alderaan Incident Consistent with Just War Theory?" Apparently so, according to the good professor, since, after all, we don't really know if Princess Leia was telling the truth that Alderaan was a peaceful planet with no weapons. Thus, it's okay to kill millions of innocent people as long as you're not sure if they have weapons or not. Guilty until proven innocent is the neoconservative standard, in fictional wars as well as real.

But rather than argue the minutia of just war theory, I just wonder what the point is. After all, if you're going to break some eggs, shouldn't we get an omelet out of it for our troubles? And if millions of fictional people are going to be murdered, shouldn't there be some good result, other than the fictional emperor gets to continue to rule?
