This act by the father surely is abuse. It goes beyond even strict authoritarian discipline. The damage caused by this kind of parental behavior can result in untold miseries in the boys future. I hope there is the possibility of family or community intervention that will lessen the boys chances of further abuse but unless there is a history of ever increasing violence inflicted on the boy by the father......the object of behavioral change must be on the father. If he cannot ameliorate his anger then a safe environment for the boy will be the only option.
