Violence is a ripple effect - FAIL

Example Fail.

“Violence is a ripple effect. It starts off as a drop in the water but soon creates a ripple effect which disturbs all the waters. This is no different than smacking a child. It may start as a smack but can trigger other violent behaviours from both the parent and the child. We need to keep our waters calm and let children have peace in their own homes”.

But why does the stopping of the supposed "ripple effect" start with smacking? Surely the "ripple" actually starts with a child's misbehavior, not a parents correction of that.
