I was thinking it gets canceled for dad committing incest with a underage daughter. That would just launch a special episode where they cast the daughter out for tempting him and end with him ask dog for forgiveness. So he didn't have to ask anyone else.

It could have ended with the rapist brother downloading 500gb of child abuse images. It would be accurate to reality.

Often, the most forceful zealot is desperately trying to hide something, and it's more than just self-loathing, although that is always an integral part of the package.
