Ones that get their hands dirty
Cicero accused him of helping Quintus Lutatius Catulus avenge himself upon Catiline's wife's brother, Marcus Marius Gratidianus, the prosecutor who had caused the death of Catulus' father. Cicero's account – given in a campaign speech attacking Catiline, who was a rival candidate for the consulship of 63 BC, – has Catiline beheading Gratidianus and then carrying the head through the city from the Janiculum to Sulla at the Temple of Apollo; later accounts embellish the tale, describing Catiline as engaging in gratuitous cruelties against Gratidianus, as described in later sources such as Livy, Valerius Maximus, Lucan, and Florus. Some modern historians doubt Catiline was involved in Gratidianus' death except perhaps in an auxiliary role, placing blame instead on Catulus and attributing the story of Catiline's involvement to Ciceronean political slander.
