Kreia, HK-47. TBH, I can't find an example of bad writing.
Shouldn't the credit for HK-47 be given to Bio, Obs is just continuing the same shtick? Kreia was indeed a stand out character in K2, but the only one on par with characters in K1, plus she's a crazy old bitch with an incomprehensible philosophy and constant whining, how anyone can believe the PC wouldn't strangle her in the first 10 minutes is beyond me. Gromnir is right, Visas was the worst, by far.
