The problem is with society, not the individual child. Violent children are often from poor backgrounds where the values are not the same as from people who are living comfortably, in this environment they may see and experience violent behaviour and they imitate what they see at home in school, corporal punishment at school would probably have little effect on their views of what degree of aggressive (whether physical or verbal) is 'normal'. Because of this I doubt that bringing back corporal punishment would be effective. Even if the child didn't see violent behaviour how are they expected to behave 'normally' at school when they don't know if they're going to get fed and clothed at home (there are currently 1.4 million children living in this kind of state of poverty) As for a solution, I don't think there is a quick fix, children act out for complex reasons, poverty, parents going through divorce, parents who abuse drink and drugs etc. To address these issues would require a complete overhaul of the welfare system and a change in thinking of the current 'the best place for a child is ALWAYS with their parents'.
