Media was a very diverse character who possesses several characteristics which were unlike the average woman during her time. As a result of these characteristics she was treated differently by members of the society. Media was a different woman for several reasons; she possessed super natural powers , she was manipulative, vindictive, and she was driven by revenge. The life that Media lived and the situations she encountered, (one could say) were partly responsible for these characteristics and her actions.
Because Media was such a different woman people in her society were afraid of her, including men. As a result of this, before Jason, she never experienced being in love. When she finally experienced this type of love she went to no end for Jason. To protect Jason and her love for him she killed the beast guarding the Golden Fleece, she killed her brother, and she left her home, family and everything she knew for him. Most women would not have gone that far for love, especially women during her time; but Media was not your average woman. All of the things she did for Jason will come into play, and partly account for her actions at the end of the play.
Although Media killed and did things that people felt were wrong it is evident that through out the play that along with her other characteristics, she was a caring and loving person. The first time we are shown this is when we discover everything she did for Jason. If she did not love him she would not have done those things. We are also shown that Media can be a caring person by the love that she had for her children. Although she killed them in the end during the play she was a mother to her children, she showed affection to them, and she did think twice before she killed them. It is because Media was a caring and loving person that she did what she did. Her feelings were hurt and her heart was broken; and she did what she felt she had to do to hurt Jason for hurting her.
When Media Jason discovers Jasons plans to marry Creons daughter she was hurt deeply. But when Creon tells her that she was being exiled we see her hurt turn into vengeance. Because Media was a manipulative person she was only needed one day to plan and execute her plan to destroy Jason. Her plan was to leave Jason with nothing, the way she felt he left her. She killed his wife to be, her father and her children. Media killed everything Jason loved and everything that would a benefit to him to leave Jason with nothing.
She did all of these things, even killed her own children because she was hurt by love.
You must look at all of these things to explain Medias actions. Without knowing her background it would be very difficult to explain her extreme actions during this play. Its not enough to say her feelings were hurt and she lashed out, you have to look at, analyze, and breakdown, Medias life and experiences.
