Weren't the devs encouraging people to play the villain? It sucks that they don't have more to show us for the evil play through if it is true but I'm sure as EA progresses that you will be able to do more(?) Alternatively, just because you sided with the druids doesn't mean you aren't "evil." I was a complete ass every chance I got and screwed over pretty much any NPC I could... I would consider that evil.
