Coil:
Maybe they are seeing those forms of punishment as a deterrent in itself, so people think more before committing a crime. For some 10 years in jail is a vacation seeing family or friends or doing work for their groups.
This only works with people who do actually think before acting. I suspect they are in the minority. Offenders who make a thought out choice to commit violent crime disconcert me more than impulsive idiots.
