So, Mick's motivation for being a serial killer (spoilers)
... is that he accidentally killed his sister while trying to help her, got abused by his dad, had to watch while his dad killed a man ... and then forced by his father to skin the body?
I guess that kind of fits with Mick later murdering families (so they could watch their loved ones die) and framing it on various people (like he did as a child).
However, it raises a pretty big question about Mick's father ... was this guy a psychopathic serial killer in his own right, or what?
