I don't think Prometheus or Orpheus thinks before they act. For example, when Orpheus is walking from out of the Underworld with Eurydice right behind him, he made the wrong decision by looking back. if he had thought about what he was doing, he probably wouldn't have looked back. Prometheus was bored of the humans and wanted to introduce fire to them, but Zeus warned him not to. If Prometheus had thought about what would happen if he put fire on Earth, he probably wouldn't have. But, he was so blinded by his desire to make things more interesting, that he went ahead and paid the price. Prometheus and Orpheus both suffered the consequences of not listening or thinking before they acted.
