They are the servant who bully Nadriska, a slave AND the propriety of the princess.
Previously she just gave them a warning and a scold.
But they became socially isolated by other servants because their didn't receive a proper punishment and the yougest try to kill themself.
(MC reputation play part too, others think MC want to see them suffer so if they ostracize them they have the possibility to be like by MC)
So MC give them a proper punishment, with this, others servant stop bulling them and they can still continue their lifes.
