I say death penalty for cold blood killing. Life in an industrial prison, basic slavery, for negligent homicide, drunk driving and killing somebody, and such. Then for involuntary manslaughter, hitting a biker on the street that wasn't necessarily your fault, or whatever, parole with a certain amount of money paid to the family of the deceased.
Theft, rape, and other such lesser crimes would be temporary work in the industrial prison and then parole with a smaller sum of money paid to the victim.
I'd go in more detail, but I am tired.
