Part of me wants to say the moral is don't trust Greek Gods.
Apparently, if the old wiki is reliable Joseph Campbell came up with the theory in pre 1904ish that the story was turned into myth after a real historical event that the Gorgon where just priestesses of an ancient snake goddess that used the evils masks to scare away non-believers and that the decapitation was really just some bloke removing their mask.
I haven't included that in my post as I haven't read the book, unfortunately, it isn't available on Project Gutenberg and I can't find any other source historical or otherwise that backs up his views.

Still more plausible than the myth!
