"A spy is to be killed, even in our days, wherever he is found. He may be killed even before he confesses. And even if he admits that he only intended to do harm to somebody, and if the harm which he intended is not very great, it is sufficient to have him condemned to death. He must be warned, however, not to confess to this. But if he impudently says 'No, I will confess it!' then he must be killed, and the sooner the better. If there is no time to warn him, it is not necessary to do so. There are some who say that a traitor is to be put to death only when it is impossible to get rid of him by mutilating him, that is, by cutting out his tongue or his eyes, but if this can be done he must not be killed, since he is not any worse than others who persecute us."
