That's a reasonable reading, but I think that there is a difference between competition and punishment. In the heat of the competition, I think I am comfortable with the idea that it is permissible to meet the fierceness of your competitor with equal ferocity. If afterwards someone is found to have exceeded their remit and punishment needs to be dealt, then I think that should be governed by a separate ethical principle.
