Oh shit yeah! That kid totally learned from his parent that violence was a solution to emotional issues. That kid is fucked for life (which is highly likely to be incredibly short) if at age six they already associate lethal violence as an appropriate solution for dealing with emotions.
That kid will learn the lesson of fuck around and find out in a life-altering/ending way soon enough. If it's starting at age six, educating that out of him is going to be a near 90° uphill battle. And that parent squarely put that mentality into him.
