Oh, the days in which I was thinking - how disturbing, yet refreshing, that they go by race rather than case to case. That demons are always evil and so forth. But yeah, it's one of those things Show seems to have "gotten over", without solving. That's disturbing. I understand it, from a writing perspective, but it could be solved in a way that goes around it. If they insist on the violence rather than exorcism, they could find some version of Cas' forehead white light thing, that'd burn the demon out and save the human, or have a weapon who only hurt the demons, or whatever - stab people in ways that would kill the demon but not them, and be stuck with piles of humans in need of stitching. If Show went with it, explored the ways in which they didn't care as much about humans (see Privilege), that could be interesting, if chilling. But no, just seems to have gotten bored with it.
