Mezentius, King of the Etruscans

Mezentius: In Roman mythology, Mezentius was an Etruscan king, and father of Lausus. Sent into exile because of his cruelty, he moved to Latium. He reveled in bloodshed and was overwhelmingly savage on the battlefield, but more significantly to a Roman audience he was a contemptor divum, a "despiser of the gods."
