one of the common tricks of Chaos, is that it convinces you that what you're doing is not working for Chaos. Plenty of Chaos cults that start thinking they are venerating the Emperor or doing something else of the good of mankind.

personally I always found the "defeating the Imperium will ultimately defeat Chaos" argument specious. Many sentient species fuel the warp with their emotions, while mankind may be numerically greater they are hardly the only species with ties to the Warp. We know the Eldar's psychic imprint was once so great that it gave birth to a new Chaos God. Nothing in the fluff has indicated that the human affect on the warp has done anything so significant. The Alpha legion got suckered pure and simple, and oh hey it was the Eldar(via the Cabal) that did it. Eldrad Uthran practically made it his hobby to screw with the fate of "lesser" races.
