Speaking of monsters... [Spoilers BG and WoJ]

So, I'm rereading Dead Beat and when Harry semi-accidentally whistles up Mab, seeking knowledge about the Erlking and Kemmler, Mab says that, and I'm quoting, he was "a madman. A monster. But brilliant."

Given what we've learned about how Mab views monsters in Battle Ground, and given that Kemmler was apparently a former Warden of Demonreach, is it possible that Kemmler was on the side of humanity surviving (or at least intending to be)? He figured out how to give a person a massive boost in power, and while it would cost a ton of lives, if it was necessary to save the world... It might not be a bad call.

Bob calls him "evil," but as Harry mentions, Bob doesn't really get morality. Evil!Bob manifests in Ghost Story as a Nazi (or the next best thing), and I doubt Butcher would paint them as a positive force given their atrocities, but I wanted to see what the rest of you guys thought about Kemmler, since I haven't seen a ton of discussion about him as of yet, given our new info.
