Here’s a wild little fact about human nature for ya:
It’s called  identification (channeling)....
basically when we pick up someone else’s traits, habits, or vibe, especially if we look up to them. Why? To feel a bit better about ourselves,for short,to reduce anxiety or increase our self-esteem  
"Unconsciously"

Ever catch yourself doing that? Like, for real ,think about it for a sec


And it doesn't stop here...a kid growing up in a tough home...You’ll probably see them copying how their friends act at school. It’s kinda like survival mode… blending in to feel safe or accepted,in most of the cases, they will interact the same way their parents treat them
