Prometheus
Hermes acts as Zeus enforcer, following his father blindly and trying to impose his rule. He threatens Prometheus with an even worse curse to try and intimidate him. Here Hermes is even more spineless than Oceanus is in the beginning. When the Oceanids turn on Hermes, saying that abandoning a friend is the worst thing you can do, Hermes still defends Zeus, saying that Prometheus' troubles aren't to be blamed on Zeus, even though they are. That kind of zealot is indicative of a tyrant.
