Aias

Sophocles' play is a famous retelling of Aias's (Ajax's) demise. After the armor is awarded to Odysseus, Aias feels so insulted that he wants to kill Agamemnon and Menelaus. Athena intervenes and clouds his mind and vision, and he goes to a flock of sheep and slaughters them, imagining they are the Achaean leaders, including Odysseus and Agamemnon. When he comes to his senses, covered in blood, he realizes that what he has done has diminished his honor, and decides that he prefers to kill himself rather than live in shame.
