Sophocles journal 1:

Oedipus originally seemed like he was a good leader. He wished to help his people, and wanted to solve their problems. However later on when he gets the news of why the gods were plaguing his city he became frustrated and lashed out towards everyone. Oedipus then, in my opinion, became a bad leader. He accused one of his best friends of conspiring against him to claim the throne, and would not listen to Tiresias who was telling the truth.

Creon seems to be a trustworthy person who wishes to help the king in anyway he can. Creon is a person loyal to his country and would not betray it. Creon seems to be sad now that Oedipus is accusing him of betrayal and heresy.

Tiresias seems to be very knowledgeable however nobody believes him. He is a very witty person and mocks those who mock him. Since he knows all the truths behind Oedipus he is disgusted with the manner he was treated when visiting his palace.
