It could be even more humorous should "evil" nations consider themselves good and their good opponents as evil. So each race would have their own perspective of good/evil bias.
Not just humorous, but it hits the nail directly on the head when talking about good or evil often being a matter of perspective. We have bounced this idea around in many of the threads here, maybe even during the GC1 and/or GC2 pre-release periods.
Admiral Willy, when you ask "My question is were the Russians evil until 1989, or were the Germans evil before 1945. Or would some of you consider the Americans evil.", do you realize how clearly you are pointing out how important perspective is? Think about this:
1) You have made the question in terms of stereotypes. While the collective picture many non German people of the time had were that the Nazis (hence all Germans) were evil, we know that was not true of all Germans. Nor was it entirely true of all Nazis. The same was, and still is, true of Russians. There are the many and varied stereotypes held by those in most other countries and there is the varied diversity between individual Russians. The stereotypes are easy to grab onto because they are so superficial, and can be comforting because of their superficiality. And "Americans" (actually limited to the USA) can be viewed stereotypically by other peoples, while we who reside in the USA see first hand how varied we are from each other. The same is true of Italians, as I learned when I was stationed in Italy for 15 months, and by extension, I consider true for any large grouping of people anyone can propose. I see this clearly because it is based on my own experience, not the collective experience of millions of others.
2) Understanding a collection of beings is much more difficult in reality than it is in a game. A game has to be based on the use of stereotypes when inventing different kinds of beings in order to underlay the conflicts that make the game work. To try to make those collections of beings as diverse as real life over complicates the code required to exhibit the varying behavior such diversity requires. Some effort can be done to show it, and the GalCiv series certainly does within the limits imposed in creating a game.
In any case, I have a learned difficulty in ascribing stereotypes to collections of real people, which is, I hope, what you were pointing out.
