How would Prometheus answer the question: "Do you think before you act?" I think he would answer: "yes." He did think before he acted. He thought about it all night while he lay on his couch. Zeus said man wasn't happy, but Prometheus saw a different side to the story. He knew that man needed fire to prosper and advance further in their civilizations. I think he knew that Zeus would punish him. Not specifically how, but just in general. He did what he did for the good of man, and they thrived into what we are now. He made a good choice when he gave man fire. Where would be be now without it?
