You don't need to be perfect at roleplaying character by character. We could use character as a defining of personality, even for your nation. Yes, there are some stories that have a conflict in the beginning but that is to bring out the true emotions and/or goals of a person or nation so that the viewer can connect. I just don't think completely random slaughter and bloodshed for no reason is logical, and I'll always stand by that. 

There has to be reasoning.
