I think AN4.233 is helpful here.
Depending on one’s intention various shades of dark and bright kamma are generated.
So instead of absolutes, until full awakening, we can choose what appears to be best (generally, less dukkha and/or more towards enlightenment), in any situation.
The intention behind the choice and action affects whether the vipāka will be darker, grey-er, or brighter.
As beings not yet awakened we live and act in a world of greys, kammically speaking.
