The Sith inquisitors should actually be dark Jedi, Sith was a race it's not a title that applies to all dark side users.
I still hate the art style.
And I don't like the crew.
So, Jango Boba, Sabine, and other famous Mandalorians, shouldn't be called Mandalorians..?
Your talking about culture I'm talking genetics, any force user can become a dark Jedi but to be a true Sith you should be able to trace your family line back to the Sith race.
Pardon me, but Mandalorians were a race. I'm not talking Culture.
See. A long time ago, there were Mandalorians and they conquered like, everything. So their culture got spread pretty far out. They also all got killed. But their culture stuck around.
Quite literally the exact same thing happened to The Sith.
See my point here? You don't have to be True-Sith to be Sith. Palpatine sure as hell isn't and damned if Vader is but they're quintessential Sith.
