Why does haemon visit his father, creon?

I believe Haemon visits his father, Creon, to ask him not to execute Antigone. Haemon was in love with Antigone, and his father, the ruler, decided to have her killed because of a wrong thing she did. She disobeyed his orders which is why he thought it was his duty to execute her, however, his son disagreed with the decision.
