Then why can’t all the times Kylo isn’t being unquestionably evil just be thrown under “Ben Solo?” Why couldn’t someone say; “it wasn’t Kylo feeling the call of the light side, that was Ben Solo momentarily showing through. Kylo is 100% evil.”

And besides that, we’ve had at least 4 unquestionably evil characters in the franchise, 2 in the OT alone; why would you want another? You don’t think it’s been played out? I think it has (and I’m not a fan of Snoke partly for that reason).
