My opinion, not really. Mind you, what you say has merit. But, the Uchihas really aren't Sayins, or Sayinesque to me. They're more like Feudal Warriors, like superninja said. Basically meaning they're based more on romanticized warriors in Japan's history. Whereas Goku, and eventually the Saiyans, were based off of Japanese mythology and folklore. And I think that's why I don't see the comparison.But regardless, interesting topic.
