Who is Hippolytus from Sarah Kane: Complete Plays and what is their importance?

Hippolytus is the prince and son of Theseus in "Phaedra's Love". As the play begins, Hippolytus is depressed. He sits in his room, watching television and masturbating. From time to time, he has sex with random people, but he has no lovers or friends. He has nothing but contempt for humanity, but the people love him. Phaedra, his father's wife, comes to him on his birthday saying she has a surprise for him. She professes her love, but Hippolytus refuses to accept. She performs oral sex on him, but Hippolytus abuses her afterward, informing her that he has gonorrhea and revealing that he slept with Strophe, her daughter. Phaedra accuses him of rape and kills herself.
