Step-by-step explanation:
The main conflict faced by Medea is her internal struggle. This internal struggle is a complex entanglement of her burning desire for revenge against her ex-husband, her deeply rooted motherly instincts, and her humane nature. Medea's conflict is multi-faceted, as she must navigate the desire to punish her ex-husband who has wronged her with the natural inclination to protect and love her children, as well as maintain her humanity through extreme emotional turmoil. Euripides' portrayal of Medea underscores the psychological dimensions of her character, displaying the intensity of her internal battle as she considers and commits actions that starkly contrast the accepted norms and values of her time.
