Free will in antiquity
In Plato's Gorgias (and in the Protagoras 345c4-e6), Socrates argues that no one does wrong willingly, one of the most famous doctrines to be associated with him. When framed in modern (Western) terms, the implication is that it is ignorance, rather that free individual agency, that is responsible for morally wrong actions.
Trial of Socrates
The totalitarian Thirty Tyrants had anointed themselves as the elite, and in the minds of his Athenian accusers, Socrates was guilty because he was suspected of introducing oligarchic ideas to them. Larry Gonick, in his "Cartoon History of the Universe" writes, ""The trial of Socrates has always seemed mysterious...the charges sound vague and unreal...because behind the stated charges was Socrates's real crime: preaching a philosophy that produced Alcibiades and Critias... but of course he couldn't be prosecuted for that under the amnesty" (which had been declared after the overthrow of the Thirty Tyrants)... "so his accusers made it "not believing the Gods of the city, introducing new Gods, and corrupting the youth.""
