Yes, he did, but Anakin is shown consistently to be angry and losing control from the death of his mother onwards.
I think it might be better that Vlad went there with murder in mind, but stopped himself from committing the crimes and instead negotiated some situation to make sure that the tribe never harmed anyone again.
I'm interested, Rex, for Scarlet.
Yes, because things were getting worst for him. Nightmared of Padme dying, greed for power, and so on. Added to that, his greatest conflict didn't arise from massacring all those tusken raiders, but from the fact that he couldn't save his mother, and now he knew he was losing Padme and wasn't able to save her. Vlad wasn't trying to save anyone.
Actually, I posted his extensive background near the end of character`s creation thread.... I assume that the only part that may be overuled by Ush is the fact that the woman Esgabath desired and his brother married was from Kuylen family.
I assume that Commisar would have his solo story, which is cool, but Gallador pre-failling to Dark Side could have a mission with some of the PT Jedi characters, which would be really interesting.
