In SG1S1E10, Daniel describes 2 types of Star gods:
the Culture bearers
The Tyrants were equaled with the Goa'uld. While on the other hand there was Thor as a friend and protector of humans.
But is this distinction sufficient?
What about Athena, Isis, Osiris, Horus/Heru'ur, Olokun, Thoth,...?
I would say that mythology portrays them in quite the favorable way, as such why do they not help the Tau'ri?
Or are they just the selected few rational Goa'uld?
