Medea is a woman who sacrificed greatly to be with Jason; the man she fell in love with and later married. She not only helped him obtain the Golden Fleece from her own country, but fled with him to his homeland to build a new life. Medea bore two children with Jason and looked to having a future with him. "But, of course, the heart of the play is the quarrel between Medea and Jason, the deserted wife and the deserting husband" (Page xiv). A future with Jason was not to be. Jason fell in love with the daughter of Kreon, the king of Corinth, and left Medea in order to wed the princess. Medea's nurse states of Medea: "And she herself helped Jason in every way. This is indeed the greatest salvation of all,- For the wife not to stand apart from the husband. But now there's hatred everywhere. Love is diseased." (Euripides 642). When Medea is tossed aside by her husband, she has declared that she will get revenge. Medea does not want to directly kill Jason, "but one that shall bring down in ruin Jason, his new bride, his children, his whole house" (Kitto 195). She feels that if she cannot be happy then no one will. Medea displays personality traits that psychologists would define as egoism, shamelessness, and remorselessness. "Egoism is an attitude of self-interest that causes a person to view objects solely in terms of fulfilling their own desires or needs" (362 Hall and 4Lindzey). Calvin S. Hall and Gardner Lindzey go on to describe in their text, Theories of Personality, 3rd edition, that shamelessness and remorselessness allow a person to disregard the opinions of others and one's own internalized standards. When these factors hold sway, a person views evil acts without compunction, and so is apt to misbehave this mental state underlies any act of ill will (362). Medea's mental state is further pushed to the edge when Kreon speaks with her and commands, "I order you to leave my territories an exile, and take along with you your two children" (Euripides 648).
