Sure, just throw your certainties in my face like the truth. You name prisons, but you forget that until recently, most children were subjected to physical violence and most of them did not go to prison.
But if you read the above correctly you would understand that it is not about breaking at all. On the contrary. It is about proportionality and that is also the hard part.
We are physical beings, why should all punishment be executed on the mind? Why is torture of the mind better? Is burden someone up with a significant debt is not seen as torture, but it is. So much so that some people commit suicide.
