Black and White Morality: Depends on the angle you look at it, really.  Outside observers would argue that the Imperials, for example, must practice a black and white morality; after all, they have an objective ethics, or so they claim, and a mathematical calculus of ethics by which to measure everything…

But then, that’s an objective ethics, which is just the core of morality.  They do have several different moral systems, albeit that a very definite majority of them hew fairly close to the knowledge-and-beauty-good, entropy-bad clade that defines the moral mainstream.  More importantly, they are entirely capable of understanding the degrees of nuance in the universe that mean that (a) just because someone is mistaken does not mean that they are evil – and that can potentially be anyone with the possible exception of the Ephors of the Curia, who were designed as self-improving incarnations of Incorruptible Pure Pureness – and (b) there is not just good and evil, there is better and worse.  Reality, as you might have gathered from Morality Kitchen Sink, is much more “White and Pale Gray and Mid-Gray and occasionally Dark Gray” versus “Black and Dark Gray and Mid-Gray and occasionally Pale Gray” than it is White vs. Black.
