My ex best friend was raised under a roof like that with religious influence. Now she is hyper sexual, rebellious, backstabs/disregards others emotions for her own benefit, and steals other women’s men. She also has huge bursts of anger and fits. I asked her why and her logic is to get back at her parents and be seen. I know her parents meant well, but it did totally backfire. I worry for her now, she blocked me on everything after I tried to have a gentle intervention.
Another aspect is it limits the amount of healthy connections kids make. I had overprotective parents and wasn’t really allowed to do much socially as a kid. I was super depressed because I’m an extrovert and my only interactions were with my cruel older sister. I was never rebellious but I think it indirectly led to my first (and only) abusive relationship in high school because I didn’t have anything I could compare it to and I didn’t think I could talk to my parents about it
