That they are, but even Jedi can fall to the Dark Side... However thats not really the question now is it.
Throw the most powerful sith up against the most powerful Jedi and who would win? I think the Sith, then after the Jedi are dead they will turn on each other until eventually everything is destroyed
Oh please...Sith getting outnumbered here.
Sith:
Pall, Ragnos, Sadow, Kressh, Hord, Nadd, Exar Kun, Revan, Malak, Sidious, Maul, Tyranus (aka Dooku), Vader, Ulic Quel-Droma
Jedi:
Mace Windu, Obi-Wan, Yoda, NJO Luke, Kyle Katarn, Arca Jeth, Vodo-Siosk Baas, LS Exile, Mara Jade, Jacen + Jaina + Anakin Solo, Cay Quel-Droma, Nomi Sunrider, Qui-Gon, Brand, Ki-Adi-Mundi, Kit Fisto, Plo Koon, Yaddle, Kam Solusar, LS Anakin and Kyp Durron.
The Sith will get killed before even knowing what did hit them. Five people with Skywalker blood are too much.
