Carmen isn’t evil because she stole stuff. She’s not even really evil. She’s one of those villainesses that has a much more benevolent goal underneath her trenchcoat.

Her methods may not have been the most savory, but by God did she get results. If not for Carmen, we would still think that Idaho was part of the Midwest. The ends justify the means—haven’t you ever watched The Shield?
