Final answer:
Euripides enhances the tragedy in 'Medea' by shifting the responsibility of the children's death to Medea herself, thereby focusing on the psychological aspects and moral considerations of her character as well as highlighting the implications of societal norms and divine influence.
Step-by-step explanation:
In Medea, Euripides challenges traditional narratives by having Medea execute her children, shifting the responsibility from external forces to her own hands. This narrative choice emphasizes the psychological complexities of Medea's character, thus bolstering the tragedy's emotional impact. Euripides engages with the humanity of legendary figures and encourages the audience to contemplate the moral and societal constructs that drive individuals to commit reprehensible acts. Through this focus, he questions the validity of antiquated conventions and deities that seem to justify such acts. Moreover, by showing the harsh repercussions of those conventions on characters like Medea, Euripides prompts his viewers to consider the consequences of unexamined social laws.
