Two equally reckless drivers can end up judged completely differently by pure chance

Two drivers run the same red light while distracted. One reaches the other side safely; the other kills a pedestrian. Philosophers Thomas Nagel and Bernard Williams pointed out that we judge the second driver far more harshly, even though the only difference was luck, not character or choice. They called this disquieting gap 'moral luck.'
