Sorry, I probably didn't make the scoring as bold as it should have been. Destruction is toward peaceful entities, as stated in my first paragraph. Tyranids are obviously not part of the rule I have already stated.

And aggression is how likely they are to attack others in this study if the others resist peaceful methods. An attack by definition harms the population. Show me a war in which no civilian suffered and I'll show you a lie. Tell soldiers have families, the land taken belonged to someone, and in any case, maybe I'll go take your home. I'll rule it better than you, so I'm coming with a big gun, taking your home, and letting you live there "in my generosity". The Tau are only between Good and Neutral because they treat their people nicely. You can't call a country that invades anything it can "Good".

To conclude: Destruction is attacking or harming peaceful creatures, Aggression is invading resisting creatures, restricted to those in this study (if given the opportunity) or similar. Discounting those too alien to morally judge.
