Catiline was a low-level rapscallion who wanted to make a name for himself by somehow violently overthrowing the consulship and perpetrating a lot of murders in the name of the disenfranchised people of Rome. Unfortunately for him, Cicero was the consul and Cicero was no Mucius Scaevola. As soon as Cicero found out about Catiline’s conspiracy, he had Catiline executed without trial.
