The Dominion have, in a very literal, here-we-have-the-physical-proof way, a directive straight from the Eldan (Wildstar's precursors-who-invented-everything race, and the reason why the game is happening where it is) to build their empire. They are simply fulfilling their divine right.

That being said, once the game really gets started, both sides are clearly doing objectively terrible things to one another and themselves, so everyone's an asshole. Of course, you never really see your own side doing horrible things, so.
