The concepts are pretty similar: two sides of a fantastical power, one side sweet, yummy, and light, used by embracing it, used by a bunch of emotionless, calm, awesome robots people (Jedi/Aes Sedai); and another side, tainted, disgusting and fiery, used by a bunch of awesome mindless killers (Sith/Asha'man).
So my question is: was the creation of saidin and saidar influenced in any way by the sides of the Force?
