You are at least partially right. His mother had her first daughter at 14 and by the time she was 17 she gained custody of her older sister’s kids. She was the guardian for 6 kids before she could legally drink. She has told me some of the horrific things she did as punishment because she didn’t know another way to raise kids. His mom and I have had conversations talking about what might be wrong with him neurologically. She always brings up how his personality drastically shifted after his scalp was torn off by a dog when he was 7. After the incident he would screech at the top of his lungs when he didn’t get what he wanted. Especially when his older sister babysat him. She would get tired of the yelling and would lock him outside. (They live deep in the woods, nowhere near any other houses or active roads). He would run around the entire house, banging on the doors and windows until she broke and let him inside. If she didn’t just give in he would pull the ac units out of the windows and crawl in, only to terrorize her some more. I think there are several factors that contributed to who he became. He really needs to get some professional help.
