Yeah, but it's the Curse of Hatred that mainly resulted in people getting evil, and that one belongs exactly to the Uchiha clan with Sharingan primary being its by-product. Uzumaki stem from Asura the same way as Senju with their Will of Fire, so they can't get evil to such a degree, yet technically there still were some antagonsts from the clan, specifically Nagato. We had an SM-using villain as well (Kabuto), and though there weren't any with 8 Gates, the ability to open them is still quite rare.
