OT: Abuse? Lets dismember their bodies, feed it to the family dog, and burn their remains.
I mean, CPS isn't a thing, so fuck, let's kill them!
Once you're already messed up in the head, you probably won't think of how wrong it is to feed it to their dog.
I can also see how it is efficient at hiding the evidence and even the dog won't question the meat that is given to him/her.
