Once upon a time there was a serial killer named Bruno Ludke . . .
A German laundry delivery man, Bruno offed at least 80 women between 1928 and 1943. When Nazi officials finally caught up with his lethal hobby, they shipped him off to a research hospital in Vienna where he was used as a human guinea pig by Nazi doctors. When they were done with their experiments, Bruno was executed by lethal injection.
That was a short story, but punishment by guinea pig-ization seems to qualify it as a goody.
Sweet dreams, and may you forever remain Crazy 4 Crazy.
