I've had gripes with the lack of context-sensitive dialogue options before... when I leveled my Operative, I was constantly amused by stealthing up and sneaking to the back of caves without killing anything, only to be dropped into a conversation about how I had slaughtered my way to the end. But this is the first time I've had a question pull me COMPLETELY out of the game. Towards the end of the BH storyline on Belsavis, you end up killing your target and rescuing the remnants of Operations Group One, some Sith and their buddies. The guy you're talking to asks if you know whether the Empire managed to free the Dread Masters. Now, I JUST CAME FROM THERE. I freed them, myself, thumbing my nose at them in the process and reporting my success to Imperial Command. However, my responses are literally "I don't know", "I doubt it" and "Isn't that your job?" I can't take credit for doing this guy's job for him, or let him know he can head home, or anything. What the balls.

LS Sith Warrior can certainly make a fair bit of sense, especially if you're consistent with it from the beginning. You can tell that Bioware anticipated some of the disconnect from the idea by the way they set up the quests on Dromund Kaas. Very minor spoilers about that... Besides, the light side options for Sith aren't really that much better than the dark side. I could choke you to death now... or I could bring you back to camp, where you will be tortured, interrogated, then probably killed anyway. Why throw away potentially valuable information?
