That's basically true, but maybe it is pretty simplistic. For example, there are tons of people in prison for 5 years, 20 years, lifetimes that don't have the intelligence, resources, or opportunity to 'have their punishment stopped'.

I find it hard to believe that a form of punishment is more just or better in any other way because it 'can, but actually won't be, stopped'.
