Finally, the sight of Agamemnon's mistress, Cassandra evokes such intense feelings of hatred as to act as yet another motive for Clytaemestra to murder her betraying husband. Clytaemestra expresses her flaming anger through the words, "here lies she, the captive of his spear, who saw wonders, who shared his bed, the wise in revelations and loving mistress," (AG, 1440-4), which clearly illustrate the culmination of emotions of Clytaemestra has for Cassandra. These three motives of motherly resentment towards the unjust murder of her child, guilty love for Agamemnon, and jealousy towards Cassandra propagate inside of Clytaemestra to kill with retribution toward Agamemnon. Clytaemestra believes her actions are right and justified, and she insists that Agamemnon deserved to die for her suffering pain. In The Libation Bearers, Orestes is a tragic hero, who believes his act of vengeance in murdering Clytaemestra and Aegisthus for the death of his father, is justifiable. Orestes is successful in avenging the murderer of his father, by plotting the assassination of his father's executioners with his sister, Electra. The chorus in the tragic play agree with Orestes before the deaths of the two murderers, "The spirit of Right cries out aloud and extracts atonement due: blood stroke for the stroke of blood shall be paid," (LB, 310-4), shows the mutual feeling of contempt and the motion of justice to prevail in both hearts of Orestes and the chorus. Additionally, after the act of violence is committed by Orestes, the support from the chorus remains, and the belief in justice is shared by Orestes as he says, "But while I hold some grip still on my wits, I say publicly to my friends: I killed my mother not without some right." (LB, 1025-9). Orestes" believes his act of retribution is right because the vicious murder of his father committed by Clytaemestra and Aegisthus was intolerable and unjustifiable.
