His step-father hit him so he, socked him back
And broke his nose, his house is a broken home
There's no control, he just let's his emotions go
By breaking his step-father’s nose, this kid simultaneously destroyed the order his parents had worked so hard to uphold. Their kid is no longer obedient, and is going as far as to punch his step-dad in the face in rebellion. The parents have no control over their child, and the child has no control over his actions.
The fact that the kid says this “house” is a broken home implies that he never really felt at home there in the first place. It was just the place where he spent his time without ever fitting in.
