After seeing what he can do as a god, I think the Athenian were scared of him rather than wanting to celebrate and worship him. I also think the dramatic tragedies that were performed at the festivals were to show the Athenians how much better their city is compared to others. In a way, I could see the Athenians wanted to show the negative aspects of other cities. They represented the play around other cities to show and persuade the Athenians that they are the best city there is. However, the purpose of the plays was to show their honor to Dionysus since he is the God of Theater. They used a playwright competition to help really show how much they want to honor Dionysus. Overall they just want to keep Dionysus happy by worshiping him and performing events that he might like
