As “dark” or “light” as something may appear, if everything is formed/comprised from an all-powerful, all-loving benevolence (which, to be honest, I’m not sure is the case), then “darkness” and “lightness” become completely irrelevant in the ultimate sense.
All that matters is whether it’s the most useful option within any given moment.
Ironically, I believe this simplistic stance allows one to navigate complexity and cut past dogma by judging each moment and person context by context, allowing one to criticize “good” people for their mistakes, and letting “bad” people rise to the occasion. This parlays into story, where the hero might have to do something questionable in order to serve a worthy aim, or when a villain can buck off their image and do something good.
I suspect it’s a harmonious way of existing throughout eons and cultures.
