Well see the problem here is that your automatically associating death with evil... It's an easy assumption to make I mean, death, darkness, destruction... Seriously though. Just because they Channel their magic through death and believe in a supremacist mind-set doesn't make them Evil... It just makes them kinda obnoxious and gothic... Like a teenager.
That same obnoxious gothic empire could also love kittens and be bloody well kind... Of course the kittens would probably be forced to survive by killing their siblings and their only really nice when you offer them tribute, and their idea of being nice is not killing you...
But does that make them evil? Naaah.
They are just misunderstood... But why do you care... Wouldn't you be Emperor? I say to hell with all these pitiful maggots before me!
Bwahahahah!
I'm gonna go sit in the corner now.
... I think you should adjust how you see good and evil and you'll see. From the mindset of the Empire... They are strong... And henceforth, by default they are good.
