To me it looked like the mother at least tried some to shield the child from some of the father's fury. She acted, to me, like she gets the shit beat out of her on a routine basis, and probably took some licks later on for interrupting his beating of the girl. If she wanted to beat the girl or see her hurt she would have hit her more than once (had to hit her at least once to get the dad to chill some) or let the dad keep going IMO. Sure she could do more, but she is probably just as much, if not more, a victim than the girl was/is. Those kinds of guys get their rocks off dominating people and making them submit.
Oh, and totally was spanked as a child with a few different objects lol. Never more than 2-3 licks though, and while they sounded scary (leather belt is loud as fuck) neither my father or my mother ever truly hurt me. I never had bruises or cuts or anything like that, and I certainly never got hit anywhere other than the ass. It was more of a threat object and didn't happen unless I earned it. Pretty fucked up to hit your kid in the stomach and legs like he did his though. He was also swinging that belt like he was aiming for the fences which is way overboard. Not to mention you shouldn't spank your kids while you are enraged with them. That will never end well for either party, as shown by his disappearing career.
