It’s more “The Jedi ideology won’t stop you from being an asshole, and the Sith ideology can be liberatory.” The entire Sith Inquisitor path is about an ex-slave rising to power, and you can lean heavily into the Sith path as a way of overcoming oppression (to the point you end up openly against the Sith Empire but the Sith base rank on power so it’s not like they can stop you).

Meanwhile, a Jedi’s over-focus on detachment from worldly desire ends up with them destroying everything they wanted, the lives of the people that love them, and the entire political project of the republic on that planet, leaving your Sith character to snark at how you’re a better Jedi than they are.
