What are the motives and conflicts of some of the characters in Sophocles' Oedipus Rex?

Creon falls into a conflict
with Oedipus because Oedipus accuses him of treason. Oedipus believes that Creon has
been plotting to take the throne since the reign of King Laius. He believes that Creon
paid bandits to kill King Laius and now Creon is allowing Oedipus to be blamed for
Laius's murder. In fact, Oedipus believes that Creon has paid Tiresias to deliver false
prophecy blaming Oedipus of Laius's murder as well as the horrible prophecy that he will
realize he has had children with his own mother. Hence, we can say that
Creon's conflict is man vs. man. However, despite Oedipus's
belief, Creon's motives are actually pure. Creon is
actually loyal to the king and quite content with the power Oedipus has extended to him,
as we see in his lines:

For now I have everything from you without fear;
but if I myself were ruler, I'd do much against my will. How then could tyranny be
sweeter to me than trouble-free rule and sovereignty?
(615-619)

Hence, we see that
Creon's conflict is man vs. man, but his motives for action are to heal the city, make
peace with Oedipus, and live peacefully in the city under Oedipus's
rule.

Jocasta is a character that has a
conflict with fate and a conflict with herself as well, making her conflicts
character vs. fate and character vs.
self. Jocasta is a victim of fate. When she
learned of the prophecy that her son would one day kill her husband and sleep with her,
she thought she was taking measures to prevent the fulfillment of the prophecy by having
her son killed. However, instead, the shepherd to whom she gave him took pity on the
baby and gave him to someone from Corinth who gave the baby to King Polybus to raise.
Because Oedipus continued to live, he fulfilled the prophecy even though Jocasta had
believed for a long time that the fulfillment of the prophecy was impossible. Hence,
Oedipus fulfilled both his and Jocasta's fate. Since Jocasta tried to escape her fate,
we can say that one of her conflicts is with fate. However, she is also in conflict with
herself because in the beginning of the play she believes as she has believed for years
that she had escaped her fate. Regardless, as the play progresses, she hears enough
evidence to learn the truth, which drives her to commit suicide, showing us that another
one of her conflicts is character vs. self. Jocasta does everything she can to escape
hearing the truth, even trying to convince Oedipus not to send for the shepherd. Her
motive is to protect her husband from the truth, as well as
herself.
