It's one part to scare a child with monsters (surely also abuse), but it gets a whole lot worse when you scare the child like that at the point where it already cries and needs support. That's kind of the worst thing that you can do.

I don't know what you experienced, but I hope it was not that bad.

It isn’t. People who do that to children are monsters and have no place in civilized society.

That's worse because now it's internalized so the parent doesn't have to even do or say anything. I'm saying because I can relate unfortunately.
