Answer:
Oedipus is intensely angry when he kills his biological father and when he fights with Creon and Teiresias for giving him bad news.
Step-by-step explanation:
Oedipus has difficulties in controlling his emotions, especially anger. That's because he is a person with an explosive temperament, who can't handle solving intrigues with ease and who expresses himself with violence. This personality trait not only leaves Oedipus a very intense character, but also leaves him a real person who often does not act rationally, being totally controlled by anger, leaving his story totally unpredictable.
Oedipus' anger may be exaggerated for us, but it was a common feature for the Greek society that created this play. That's because the Greeks at that time lived in a very violent time with several invasions and stress. Watching a character unleash his anger in a grandiose way could be somewhat comfortable for the Greeks.
