scene 1 Anwhy does creon feel so differently toward polyneices and eteocles?

Oedipus, Antigone and Ismene's father, also had two sons, Eteocles and Polynices. Upon his death, it was agreed that they would each take the throne from one year to the next. After the first year, however, Eteocles, the elder, refused to step down. Polynices and six foreign princes charged the seven gates of Thebes and all were defeated. The brothers killed each other in a duel, leaving Creon king. Creon ordered Eteocles buried in honor and left Polynices to rot. Furthermore, any who attempt to bury him will be put to death.
