Trying to get back at
Zeus via his mistresses was certainly the wrong move especially since
Hera didn't seem to differentiate between mistresses and victims. Often times, the things that
Zeus did to hide his infidelities were just as bad as anything that
Hera would have done to them. He seemed to have a fetish for turning people into animals or turning himself into one.
The time when
Hera,
Poseidon, and
Hades captured
Zeus and wouldn't let him go until he swore to be a better ruler seems to have one been one of the few times that they really managed to flip the tables. Although
Zeus was apparently much stronger than his siblings,
Zeus did not seem able to undo what
Hera had done.
Hera's curses seemed to stick.
