Throughout the play, the audience cannot help but feel merciless towards Pentheus. In his opening scene, Pentheus does not heed the warnings bestowed upon him by Teiresias and Cadmus. Before Pentheus even meets Dionysus, Teiresias offers him wise advice:
'So, Pentheus listen to me. Do not mistake the rule of force for true power. Men are not shaped by force. Nor should you boast of wisdom, when everyone but you can see how sick your thoughts are. Instead, welcome this God to Thebes. Exalt him with wine, garland your head and join the Bacchic revels'(19).
Cadmus carefully tries to persuade his grandson by adding, 'For even if you are right and this God is not a God, why say it? Why not call him one? You have everything to gain from such a lie'(20). Pentheus shows no respect for the elderly or their wisdom by replying, 'Go! Run to your Bacchic revels. I want none of your senile folly rubbing off on me!'(21). This response alone reveals a great deal about his disposition. He will not let any 'old fools' tell him what to do. However, it is ironic that Pentheus' rejection of the advice of these 'old fools' proves to be his first step towards his fatal end.
The next scene brings Pentheus and Dionysus face to face. Pentheus starts the conversation thinking he has the upper hand because he has more power over the situation. 'Untie his hands. Now I have him in my net, no amount of agile tricks can help him slip away' (25). However, it is clear to the audience that Dionysus is in control. He is provoking Pentheus by responding with quick, saucy remarks.
