I must point something out here; I am all for making life a living hell for murderers and rapists etc. But what for those who are either in prison because, say, they refused to pay a bill which everyone else would not have paid, or agrees with them not paying? And what percentage (a % we will never know) of people who are innocent, but in-prisoned?
The level of severity of punishment should be down to the type of crime commited. It should never be a hell for all or nothing.
