Greek women used to cover their faces with lead, which increases agression. Greek women may have really been more vain flighty than average.A lot of it also has to do with the function of religion in early societal development as well, particularly in the context of how each culture was in a different environment geographically speaking. The groups of people we collectively label under the "Norse" umbrella had very harsh environments to live in, particularly in the winter, which does much to explain why their gods are all largely more serious and most of their mythology is centered around preparing for an oncoming cataclysmic event; interdrama does still occur, but it ultimately ends up meaningless in the end when the endless Winter arrives.
The greeks, conversely had a much milder and less varied climate, outside of the storms/uncertainties of sea travel and the inevitable results of stuck in a bunch of warring city states and nearby countries; their gods are therefore used as examples of the dangers of being a terrible person (in their eyes), or to explain freak acts of nature like volcanoes or storms in the sea. Yes, the norse had sea gods as well (which were also some of the more unpredictable one), but there's a reason the more "hostile" gods to humans in the greek pantheon were related sea travel and warfare, or just used as a scapegoat for lampshading societal sexism; because nothing says 'women' like vain flighty goddesses who turn women they think are prettier than them into animals, or grow insanely jealous and blame them for their husband's philandering, and even claim that the very existence of women was to be made out of clay and perpetually unhappy as a punishment to men for their crimes against the gods...am I right fellas?
