As it seemed to me, in the construction of the image of the main character, Euripides uses his favorite method, common to all his so-called "drama of revenge" (Medea, Hecuba), The essence of this technique is that, despite the legitimate desire to take revenge, lawless, the heroine possesses a wicked passion for revenge, which in the final turns the situation in contrast to the one planned at the beginning, depriving the revenge that has come about of any legitimate excuses. This effect is achieved, as a rule, by the fact that the criterion for assessing all acts of tragedy is the yardstick of ordinary human morality.
