I'm going to blame to Zeus because Zeus can give fire to humans for free. But Zeus is not giving to humans so Prometheus just took without permission. So Zeus give Pandora and golden box to Prometheus's brother to revange also Zeus put all the bad things inside for example envy, jealousy, old age, spite, varity, distrust, despair, poverty, deceif and disease to everybody however he could done to Prometheus and his brother Epimetheus.
