It's a moral maze. I guess it's down to every group really. I'm not even sure how I see it at my table, and we don't even track a Morality score (anyone with a Force-sensitive career is either Light or Dark at any given moment, with attendant bonuses or penalties).
As Desslok points out above, it seems FFG want ANY remotely violent thought or deed to count towards conflict... even though in the films we see Luke slaughter his way through stormtroopers and skiff guards and Ben chops Ponda Baba's hand off, without any real angst ensuing.
As for the 'sentience of droids' thing, that interests me a great deal, because it's NEVER addressed in the films, and doesn't even seem to be addressed in the EU, as far as I can see. (One of the EoE adventures - the one in the GM screen - does have a creepy horror-style scenario where the unhappy droids have slaughtered all the meatbags and declared Claptrap's Robot Revolution, however).
The films just gloss over this. Artoo and Threepio don't get medals any more than Luke's X-Wing or Han's blaster pistol do.
