Pemry Janes
Sage
To the ancient Greeks, the Persian empire was pretty evil. If the empire is looking to add you and yours to their dominion, it's reason enough to declare them evil. I think this term should be seen as subjective. The empire itself isn't going to think it is evil, it will instead point out all the benefits or being part of the empire or claim instead that they were the ones threatened.
A lot of Roman wars were 'defensive', for example.
