These injunctions are not contradictory...

These injunctions are not contradictory, for whosoever must be punished for the crimes which he has committed, suffers his injury not through the ill-will of the judge but on account of his evildoing. His own acts have brought upon him the injury that the executor of the law inflicts. When a magistrate punishes, let him not harbor hatred in his breast, yet a murderer, when put to death, should consider that this is the fruit of his own act.
