CREON I know it too, and it perplexes me. To yield is grievous, but the obstinate soul That fights with Fate, is smitten grievously. (1095-1099)
Although Creon wants to resist, he knows better than to fight fate. He has learned from Oedipus’s mistakes.
ISMENE O sister, scorn me not, let me but share Thy work of piety, and with thee die. ANTIGONE Claim not a work in which thou hadst no hand; One death sufficeth. Wherefore should'st thou die? ISMENE What would life profit me bereft of thee? ANTIGONE Ask Creon, he's thy kinsman and best friend. ISMENE Why taunt me? Find'st thou pleasure in these gibes? ANTIGONE 'Tis a sad mockery, if indeed I mock. ISMENE O say if I can help thee even now. ANTIGONE No, save thyself; I grudge not thy escape. ISMENE Is e'en this boon denied, to share thy lot? ANTIGONE Yea, for thou chosed'st life, and I to die. (544-556)
Antigone chooses both her own destiny (death) and her sister’s (life). She demonstrates that there is such a thing as free will, after all.
ISMENE I scorn them not, but to defy the State Or break her ordinance I have no skill. ANTIGONE A specious pretext. I will go alone To lap my dearest brother in the grave. ISMENE My poor, fond sister, how I fear for thee! ANTIGONE O waste no fears on me; look to thyself. (82-85)
While Antigone feels empowered to impact her own destiny, Ismene does not.
