The introduction of the code breaker was a positive (“good is a point of view”). Ep8 looked to be set up to tackle this question then reasserts who is good & who is bad.
And the DO tackle that question pretty hardcore when Luke is talking about all the ways the supposedly good Jedi were bad. The question isn't who is good, it's "what actions are good?"
They tackle half. When Luke talks about the bad things the jedi have done. To tackle the question we have to know how the Sith/First Order (or just Kylo) are doing good.
