I wouldn't call C'kayah really evil, per say, unless you'd call John Gotti evil.
He started out as a thief (motivated by his desire to reattain the luxuries he had when he was the silver merchant A'rela Nereh's favorite sweet young thing), was run out of Ul'dah because he was clumsy with the politics of who to steal from and who not to steal from, settled in the Shroud, made connections with the local Duskwight and Moonkeeper clans, and started to smuggle.
In the last year he's become much more of a business man, to the extent that his current organization has a legitimate import/export front and is chartered by the Syndicate. As the organization grows, his aims and desires mostly are for things that will continue to amass power for it, though he still indulges in the occasional theft (or worse), driven by motivations he doesn't quite understand.
