That or they become so desensitized, they start to mimic the behavior..not just with kids like you mentioned. Look at all the adult men who think trash talk, they learned as adults, or very adult porn, where women are humiliated, pushed around, and forced to be submissive, made them desensitized and normalized this kind of abusive language and control. One only needs to witness any part of the bear discussion to see it. Or any woman seeking views for the payout on social media by doing nothing but posting soft core porn images and validating men on their page. Their comments sections are full of men who use the same kind of abusive language. They learned it from each other as adults.
