I think of it kind of like D&D alignment, but with cool instead of lawful.

Cool good: Han Solo
Cool neutral: Boba Fett
Cool evil: Darth Vader
Meh good: Admiral Ackbar
Meh neutral: Jawas
Meh evil: Moff Tarkin
Uncool good: Uncle Owen
Uncool neutral: that droid that’s just a box on legs
Uncool evil: Jaba the Hutt
