The Bacchae, its so old (Euripides wrote it I think?) but the values of the story are still in affect.
The Baccahe extremely summed up...
Ruler doesnt believe in Dionysus (God of pleasure/whine/etc) existance/forbids worship of Dionysus. Dionysus appears in human form to the ruler, human Dionysus tries to reason/convince the ruler, but the ruler is too straight laced/doesnt believe Dionysus. Dionysus makes the ruler go crazy, he then dresses up as a girl to see the Bacchae (crazy women) as they celebrate a holiday to Dionysus. Dionysus bends a tree for the ruler(lol), and the ruler sits atop the tree. Dionysus then calls out to the Bacchae, who run to the tree ,get him down, and tear him apart by his limbs. His mother rips off his head, puts it on a pike and returns home. Her father, the founder of the land the ruler previously reigned over made her (a crazy bacchae women) come to, and realize she decapitated her son.
The moral is basically if you tighten the strings too much on yourself, youre bound to break. Im a Catholic, but the fact we still dont let priests get laid is ONE of the modern examples. Catholic priests almost always TRY to repress their sexual desires, but that is NOT normal. Eventually some of them WILL break.
