What's wrong with Palpy being a Sith? Just curious, nothing against him not being a Sith.
Any time you take a character, and say "WAIT! There's a whole class of characters just like them!" it lessens that character.
Greedo comes from a species of all bounty hunters.
Jabba comes from a species of all crime lords.
Palpy comes from a club of evil wizards.
Boba comes from a planet of bad ass whatever he is (retconned at some point).
It makes them boring.
