Do harsh punishments do anything other than slightly affect the expected value calculation for a sociopath? For the majority of people, the reason they don't commit arbitrary crimes is a feeling that it would be wrong. I don't kill people because I might get 25 to life. I don't kill people because killing is wrong. When I look at crimes of passion or necessity, these cannot be stopped by harsh penalties. A fit of jealous rage doesn't consider the prison term. Hunger won't stop theft. The only place harsh punishments could stand to be effective are crimes which have no moral component. For such crimes ALL persons make an expected value calculation, like a sociopath makes for crimes than an ordinary person would consider immoral.
