There's a saying that bad people can oppress the weak and act without restraint because there are no competitors in their ecological niche.
Everyone else has morals, and he doesn't have any, so he can live easily and freely.
But once everyone discards their morals and can do whatever they want, do those evil people, who had nothing but their lack of morals, really have any room to survive?
Jiang Yinyin's father is just such a hopeless waste.
He can't really be considered a truly evil man, nor does he have the capacity to commit evil deeds; he's just a pathetic gambler who has lost everything. Even the lowest loafers on the street can bully him, literally defecating on his head.
The only ones he can bully are his wife and daughter.
The biggest, or perhaps the only, skill of this kind of person is to act shamelessly.
