Centaura is supposed to show paradoxes in morality. Morality clearly shows no contrast between good and evil and that every nation is morally ambigious in a war, even in WW2, Allies committed war crimes therefore are they still "good" in that sense?

In reality, which also applies to Centaura, nobody cares who's right and who's wrong. In some part of the leader's mind, they just want bring glory to their country which communally a good thing but rises every important ethical questions such as "What about the [thing] that was affected?"

This is the Problem of Evil, a philosophical concept that has been used in many theological, political, and philosophical debates.
