In the first scene, King Creon is firm in his belief that everyone should always be loyal to their kingdom, and those who aren't shall be punished. This caused conflict as it creates a sense of disrespect towards Polyneices and his living family (Antigone especially). In the second scene, Creon further expresses this hate for treason when he's explaining to Antigone why Polyneices doesn't deserve a proper burial.
I have nothing but contempt for the kind of governor who is afraid, for whatever reason, to follow the course he knows is best for the state. As long as I am king, no traitor is going to be honored with the loyal man.
If that is your will, Creon son of Menoeceus, you have the right to enforce it: we are yours.
That is my will. Take care and do your part.
Polyneices made war on this country. Eteocles defended it.
