They have sentience. They have self preservation instincts. Whenever they're in trouble, C3PO's biggest fear is that he's going to "die". Despite the fact that he is the least likely in danger of all the humans around him. If they got captured, the worst that might happen to him is he would have his memory wiped and be reprogrammed to serve the empire. When they crash land on Tatooine, the first thing that happens is they get captured and sold to Luke's family. Who then install "restraining bolts" on them to keep them from wandering off. When he gets back from dinner, the first thing Luke does is turn on the restraining bolt that wakes up C3PO. Suggesting it is like a little electric shock. Like a shock collar. This suggests semi-inhumane treatment. If droids are basically appliances for human needs, why give them personalities and sentience? R2D2 almost seems like he can feel pain. Especially when the jawa shoots him. And the droids in Jabba's palace DO feel pain. Which also seems like an odd thing to program a droid to feel. What purpose does it serve unless it is to keep them in line through threat of pain? Would something like a "restraining bolt" even be necessary if they were just appliances? Most people don't need to worry about their refrigerator wandering off. And then there is the scene in Phantom Menace where droids are being picked off left and right to fix the queen's ship and when the repairs are done, she personally thanks R2D2. So the humans at least acknowledge that the droids are sentient beings in comparison to something like a toaster. Does this mean that droids exist in some sort of odd limbo between alive and not alive? They have consciousness and sentience but they have no rights as living beings. What do you think?
