...I have proclaimed, just now, the following decree to our people concerning the two sons of Oedipus. Eteocles, who died fighting for Thebes, excelling all in arms: he shall be buried, crowned with a hero's honors, the cups we pour to soak the earth and reach the famous dead. But as for his blood brother, Polynices, who returned from exile, home to his father -- city and the gods of his race, consumed with one desire -- to burn them roof to roots -- who thirsted to drink his kinsmen's blood and sell the rest to slavery: that man -- a proclamation has forbidden the city to dignify him with burial, mourn him at all. No, he must be left unburied, his corpse carrion for the birds and dogs to tear, an obscenity for the citizens to behold! These are my principles. Never at my hands will the traitor be honored above the patriot. But whoever proves his loyalty to the state: I'll prize that man in death as well as life. (215-235)
How does Creon use juxtaposition to further his point about the two brothers?
