I think the notion of gray Jedi can work – if such characters are clearly portrayed as antiheroes/antivillains with questionable morality.
If that’s a temporary state. Eventually you should have to pick a side, because that’s how the dark side works.
I mostly agree. Guess it all boils down to what picking the dark side entails. I’m not a fan of every darksider being a 2-dimensional sociopath who craves UNLIMITED POWA!!! for the sake of UNLIMITED POWA!!!
