Tyrannicide can also be a political theory and, as an allegedly justified form of the crime of murder, a dilemmatic case in the philosophy of law, and as such dates from antiquity.[5] Support for tyrannicide can be found in Plutarch's Lives, Cicero's De Officiis,[6] and Seneca's Hercules Furens.[7] Plato describes a violent tyrant as the opposite of a good and "true king" in the Statesman,[7] and while Aristotle in the Politics sees it as opposed to all other beneficial forms of government, he also described tyrannicide mainly as an act by those wishing to gain personally from the tyrant's death, while those who act without hope of personal gain or to make a name for themselves are rare.[8]
