I could see that, especially with the whole "Darkness will return" theme. However, I'd like to see it more as a "The net good in the world = The net evil in the world". Thus, the evil of something like a Death Stalker could counteract the good in several humans.

It is also possible, as a few people have stated above, that Remnant has a way of maintaining a natural balance, and Human/Faunus civilization (and, thus, order) disrupted a naturally chaotic world. Grimm could just be a byproduct of that.

However, I personally just like the idea of "Grimm" being the force of evil in the world, and the Creatures of Grimm being manifistations of that. I think it would make a smooth and interesting narritive... but then again, we're dealing with Monty here, and he can make just about anything smooth and interesting.
