Answer:
Antigone is a very stubborn character. However, her motives are good. She wants to make sure her brother is treated respectfully in death. But (no than) she disobeys the king's orders too. She is not willing to except treating Polyneices badly because of choices he made while living, which is why he was killed in the first place. Rather than follow the king's wishes, she follows her heart. Which gets her into trouble. She doesn't care, though. She excepts her sentence of death and does not waver.
