Cicero, Letters to Brutus, 23 (I.15), 43 BCE
“There has been no civil war in our state which I can remember in which, regardless of which side was victorious, there was not some hope for a government in the future. In this conflict, however, I could not easily confirm what government we would have if we are victorious, but there will surely never be another if we lose.
This is why I put forth harsh legislation against Antony and Lepidus too, not so much for the sake of vengeance as to frighten the lawless citizens among us from besieging their own country and to prepare for posterity a reason why no one should desire to emulate such insanity.
Although this idea certainly was not more mine than everyone’s, in one way it seems cruel: the fact that children, who have earned none of this, suffer the same punishment as their parents. But this is an ancient practice which has existed in every kind of state. Even the children of Themistocles lived in deprivation! If the same penalty attends citizens condemned in court, how could we possibly be easier against our enemies? And what can anyone complain about me when he would have to admit that if he had defeated me he would have treated me worse?”
nullum enim bellum civile fuit in nostra re publica omnium quae memoria mea fuerunt, in quo bello non, utracumque pars vicisset, tamen aliqua forma esset futura rei publicae: hoc bello victores quam rem publicam simus habituri non facile adfirmarim, victis certe nulla umquam erit. dixi igitur sententias in Antonium, dixi in Lepidum severas, neque tam ulciscendi causa quam ut et in praesens sceleratos civis timore ab impugnanda patria deterrerem et in posterum documentum statuerem ne quis talem amentiam vellet imitari. quamquam haec quidem sententia non magis mea fuit quam omnium. in qua videtur illud esse crudele, quod ad liberos, qui nihil meruerunt, poena pervenit. sed id et antiquum est et omnium civitatum, si quidem etiam Themistocli liberi eguerunt. et si iudicio damnatos eadem poena sequitur civis, qui potuimus leniores esse in hostis? quid autem queri quisquam potest de me qui si vicisset acerbiorem se in me futurum fuisse confiteatur necesse est?
