What that means is that the offenders who create the most harm (by being least likely to be caught, and generating the greatest hauls of loot) are also those with the greatest disutility of punishment.
Maana yake ni kwamba wahalifu wanaoleta madhara zaidi (kwa kuwa na uwezekano mdogo zaidi wa kukamatwa, na kuzalisha mali nyingi zaidi za nyara) pia ni wale walio na ukosefu mkubwa wa adhabu.
