It's wrong to hit others.
Bob's son Biff punched a classmate in the nose at recess.
Bob wants to impress on Biff that hitting his classmates is unacceptable.
Biff calmly explains that violence is unacceptable and that he is disappointed in Biff's behavior.
Bob spanks Biff and threatens to do so again if Biff ever raises a hand to a classmate.
Biff is embarrased by his behavior and sincerely promises to never hit anyone again.
Biff never again hits a classmate but when he grows up Biff uses spanking to control his children's behavior.
