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.
Star Wars NEVER asserts that "good is a point of view" - It asserts, over and over, that "good is a point of view" is the mentality of evil/selfish/nihilistic people.
Meant more that in the original trilogy people were clearly good or bad (except Lando, vader killing palatine). Prequel, who is good & who is bad is less clear, like you say action
