Plutarch, Life of Brutus 29
“Faith in his sense of principle provided was the foundation of his great good will and fame. For Pompey the Great was not expected—should he overcome Caesar—to put down his power in deference to the laws, but people thought he would keep his political control, smooth-talking the people with the name of consulship or dictator or some other more palatable office.
Now it was imagined that Cassius, an eager and emotional man often distracted from justice by profit, was pursuing war and adventure to create some dynasty for himself rather than freedom for his fellow citizens. For in an earlier time than that, people like Cinna, Marius, and Carbo, even though they made their own country their victory prize and source for spoils, they warred by their own confession for tyranny alone.”
καὶ μέγιστον ὑπῆρχεν αὐτῷ πρὸς εὔνοιαν καὶ δόξαν ἡ τῆς προαιρέσεως πίστις, οὔτε γὰρ ἐκεῖνος ὁ μέγας Πομπήϊος, εἰ Καίσαρα καθεῖλεν, ἠλπίζετο βεβαίως προήσεσθαι τοῖς νόμοις τὴν δύναμιν, ἀλλ᾿ ἀεὶ τὰ πράγματα καθέξειν, ὑπατείας ὀνόματι καὶ δικτατορίας ἤ τινος ἄλλης μαλακωτέρας ἀρχῆς παραμυθούμενος τὸν 5δῆμον· Κάσσιον δὲ τοῦτον, σφοδρὸν ἄνδρα καὶ θυμοειδῆ καὶ πολλαχοῦ πρὸς τὸ κερδαλέον ἐκφερόμενον τοῦ δικαίου, παντὸς μᾶλλον ᾤοντο πολεμεῖν καὶ πλανᾶσθαι καὶ κινδυνεύειν αὑτῷ τινα δυναστείαν κατασκευαζόμενον, οὐκ ἐλευθερίαν 6τοῖς πολίταις. τὰ μὲν γὰρ ἔτι τούτων πρεσβύτερα, Κίνναι καὶ Μάριοι καὶ Κάρβωνες, ἆθλον ἐν μέσῳ καὶ λείαν προθέμενοι τὴν πατρίδα, μονονουχὶ ῥητῶς ὑπὲρ τυραννίδος ἐπολέμησαν.
