Why would there be good guys and bad guys? World War 2 was pretty easy to judge because the leaders on all sides were practically cartoons, but in most wars, the "bad guys" are whoever has the flag that doesn't look like yours. I could say a lot more and take this thread in a direction far away from Glest, and probably say some inflammatory things about some of the boondoggles the militaries of the world are currently in, but instead I'll leave you with a quote and recuse before I start something bad.
A man's called a traitor - or liberator
A rich man's a thief - or philanthropist
Is one a crusader - or ruthless invader?
It's all in which label
Is able to persist
There are precious few at ease
With moral ambiguities
So we act as though they don't exist
-- "Wonderful", from the musical Wicked
tl;dr: Nobody.
