Oedipus Tyrannus (he was not a king but a tyrant) is not very weird. You'd have to expel from your mind all the nonsense that you inherit from Freud if you're going to read it.
If you want weird/terrible, try the House of Atreus, but there are no extant dramatic works about any before Agamemnon.
Speaking of which, you may like Iphigenia in Aulis, but sadly, unlike in other versions of the tale, she is saved by Artemis at the last moment.
I'm tempted to suggest something extremely weird/terrible just for the fun of it.
Oedipus Rex, anyone?
