I think the abused often abuse. They’re just desensitized.
I don’t mean this in generic terms as I know there are many who have been abused that could be reading this. 
I meant, I’m a context where someone is abused by a perpetrator and society holds that abused to high regards and doesn’t acknowledge the wrong doing to the victim, I feel like they internalize the message of : Abuse=power.
Thankfully in the UK, victims have a much stronger voice and reassurance to get acknowledged, especially children.. and so the victim grows up knowing that they and their childhood is valuable and the perpetrator is in the wrong.
Internalized messages by the consequences put in society.
I’m so glad the child is seeing the consequence of his fathers actions. His childhood matters.
