There's a reason we rarely bring the Zalmunna into serious RP, or have to severely throttle them back when we do, though. They pretty much CAN'T be played as they're meant to be, without wrecking things. Nor do I view their less savory actions as being in any way cute or charming.
Sayik...is a whole 'nother matter. But actually, while I agree that he makes a great character, I don't really like him, either! And I do think he gets away with way, way too much, without getting kicked for it nearly as often or as hard as he deserves.
