Once this wild love, happiness, passion, and pride is taken away the tragedy really breaks her down and makes her very vauerable to hate. .
The whole tragedy in the end is caused by how powerfully her emotions effect her as a person. She lives by them, she sacrifcices the ones she loves for one mans love, who in the end doesn't return the amount of "do anything for love" feeling. He doesn't just think about Medea and how much he loves and would do anything for that love to be returned and lived. He is more for himself. in that although he loved Medea and knew she greatly loved him in return.
Ultimately he was out for his own social status. He may not have loved his new wife, but this wife brought him money, a ealthy home and a high ranking. .
This is almost kills her. in the sense all she had lived and sacrificed for him was all a waste. She lost the feeling of being greatly loved.
For a woman who was this emotional, and lived through her emotions this wasn't a pleasant event. It start the tragedy. She began as a powerful godess who got what she wanted and if that failed she would risk anything to get what she so greatly desired when this feeling or desire of hers not fulfilled she snapped.
Her emotions take her over. Once again she is out to get what she wants and wouldn't stop at anything to get it.
This great desire was not one for love or eternal happiness but for revengeon the one who abused her love. So i agree to the point that this tragedy was brought on by her emotions. The words that it was brough on by her inability to control them is incorrect. Her actions are affected by her emotions. This is because she is a woman who lives by her emotions. Its not her ability or inablity to control them that causes the ultimate tragedy.
