In the myths, Hercules is driven insane and slays his children with Megara (and in some versions, Meg herself as well). In the show, he could easily be insane like Zelena, Regina or Arthur.

In the Disney movie, Megara works for Hades because she sold her soul to him. But then she repents and sides with Hercules out of love. The same could hold true in Once.
