No, the harsher the punishment, the more likely they are to commit crime afterwards. Building up resentment and breaking any facility for criminals to feel empathy by treating them appallingly is no rehabilitation approach.
Re-offending by the guilty party yes but I meant to be made an example of for other before thinking happy slapping is a great idea...
And they shouldn't commit crimes in the first place if they can't handle prison sentences. Large or small.
