Man, the “only a Sith deals in absolutes” line was really one of those things that sounded a lot better on paper than it actually turned out to be.
Even beyond the obvious self-contradiction, “dealing in absolutes” is such a weird attribute to describe as unique to the Sith… Like, the identifying mark of a Sith isn’t their hunger for power and control, nor their mastery of the Dark Side, it’s that they aren’t moral relativists? Really?
