Not one of them had bothered to think about what they were doing, and they'd nearly gotten a classmate killed. They would have, if not for Percy. That, in short, made them terrible people. Their classes were silent and gloomy; their teachers looked on them with concern as they trudged around listlessly and barely listened to the lectures. None of them were doing very well on any of their work, but no one really had the heart to call them on it, not even Snape.
