How are the sisters similar to other archetypal antagonists

According to a different source, this question refers to the play "Antigone."

In Antigone, we meet two sisters, Antigone and Ismene. The sisters have recently lost their two brothers. Normally, this would mean that the sisters will mourn them and give them the funeral rites that are traditional in this situation. However, Creon, the king of Thebes, has outlawed this.

The sisters are similar to other archetypal antagonists because they are diametrically opposed to each other. While Antigone believes that the right thing to do is to disregard the law and take care of her brothers, Ismene believes that the law is supreme and should not be trifled with.
