The Bacchae
Dionysus, in my opinion, was portrayed in a condemning light in this play. He temps the king, Pentheus, to get dressed and come with him to Mount Cithaeron and see the Bacchic women that have been worshiping Dionysus. The king previously established that he was against everything happening on the mountain, and yet Dionysus was able to persuade him into personally investigating. Why would he lure the king to his death instead of just kidnapping him and abandoning him elsewhere? How did Pentheus's mom, Agave, get involved? The descriptive language used to describe her murdering her own son was so vivid and barbaric, while the language used to describe her realization of what she had done was heartbreaking. The only people in the kingdom who saw Dionysus as good were the king's father, Cadmus and Tiresias.
