In greek tragedy, hubris is excessive pride or vanity that causes characters to overstep their boundaries and then fall in vain. in antigone, creon displays hubris when he takes matters of life and death into his own hands rather than leave those decisions to the gods

D) CREON: For Polyneices 'tis ordained that none Shall give him burial or make mourn for him, But leave his corpse unburied, to be meat For dogs and carrion crows, a ghastly sight. So am I purposed; never by my will.

I would say this excerpt shows clearly his hubris - he thought that his laws were far more important than God's laws, in which he showed excessive pride.
