Milord I’ve seen parents doing awful things to their offspring. “It’s for your own good”, “tomorrow you will thank me” “a day this suffering will be useful “ etc
I think there are graded levels of this. My parents did things that I am sure I thought were awful. I once told my mother that she was the meanest mother in the world. (We joke about that now). I heard these things about studying, doing homework, staying away from the "bad" kids, not getting girls pregnant, not skipping school, not drinking, not doing drugs, etc. Turns out they were right although I did not always like the pressure and coercion. i.e. "If that project is not done, you can't go out until it is." My parents and I get along well.
It is not possible to make generalization that apply to all equally.
