Corporal punishment must be used as part of a wider strategy and at the correct time: when other immediate discipline has failed; when the child understands their behavior and has had an opportunity to explain it; and after an initial warning and opportunity for the child to repent. Crucially, the person delivering the punishment must not be angry at the time. This undermines much of the hysterical argument against corporal punishment.
Serious physical injuries only occur where disciplined, strategic corporal punishment becomes child abuse. There is a strict line between the two (see above) and to ignore it is deliberately misleading.
Cons
It is never right to hit a child. Even the power of physical punishment to teach a child the difference between right and wrong is dubious; a young child may learn that the adult is displeased, but not why. Spanking will cause a state of extreme distress and confusion which makes it less likely they will analyses their behavior with clarity. In older children disciplined at school, a physical punishment is likely to provoke resentment and further misbehavior.
No matter how orderly you make the beating of a child, there are a number of adverse effects. They will lose trust in the adults who administer the beating; they learn that force is an acceptable factor in human interaction; they feel humiliated and lose self-respect; and they build up resentment that cannot be resolved at the time but may lead to severe misbehavior in the future.
The actual physical damage inflicted via corporal punishment on children can be horrifying. Examples can be found of students needing treatment for broken arms, nerve and muscle damage, and cerebral hemorrhage. Spanking of the buttocks can cause damage to the sciatic nerve and therefore the leg to which it leads
