The only "good" that comes to anybody in a war is economical gain. That's certainly not actually a good thing. One of the most scary things about war is that somebody is always making money from war. Governments poor billions of dollars into their military. The money doesn't just disappear. It's almost always going to private companies. This means that it is in these companies' interest to start and continue wars. Naturally, these companies are usually close to the government and often times people from these companies get into high ranking positions. It is a sick and dirty business.
