" There's something easy about the idea that vampirism is some kind of disease- then they can't help it if they attack us, that they commit murders and atrocities, that they can only control themselves sometimes. They're sick; its not their fault. And there's something even easier about the idea of demonic invasion, something forcing our loved ones to do all manner of terrible things. Still not their fault, only now we can destroy them. But the third option, the possibility that there's something monstrous inside of us that can be unleashed, is the most disturbing of all. Maybe its just us, us with a raging hunger, us with a couple of accidental murders under our belt. Humanity, with the training wheels off the bike, careening down a steep hill. Humanity, freed from the constraints of consequence and gifted with power. Humanity, grown away from all things human. "
