Why does Creon order Antigone to be killed? She abandoned her sister and left her alone.
She disobeyed his command and buried her brother.
She fought by her brother Polyneices's side in the war.
She spoke highly of her father, which was frowned
upon.

She disobeyed his command and buried her brother.

Explanation:

As the text explains, “To bury the dead was a most sacred duty, not only to bury one's own, but any stranger one might come upon. But this duty, Creon's proclamation said, was changed in the cause of Polyneices to a crime. He who buried him would be put to death.” When Creon learns that Antigone has defied his order, he has her killed.

the reason some people sacrifice their own life for another person's life could be that they are in love with them and would do anything to keep them safe a protected even if that means risking their life in the process
