(It is plain that to suffer and to do injustice are both bad, for the one is to get less and the other more than the mean amount, which corresponds to what is healthy in medicine, or to what promotes good condition in gymnastics: but, though both are bad, to do injustice is the worse; for to do injustice is blamable and implies vice (either completely formed vice, what we call vice simply, or else that which is on the way to become vice; for a voluntary act of injustice does not always imply injustice), but to have injustice done to you is no token of a vicious and unjust character.
In itself, then, to be unjustly treated is less bad, but there is nothing to prevent its being accidentally the greater evil. Science, however, does not concern itself with these accidents, but calls a pleurisy a greater malady than a stumble; and yet the latter might, on occasion, accidentally become the greater, as, for instance, if a stumble were to cause you to fall and be caught or slain by the enemy.)
