Sim, alguns dróides poderiam. Havia um hardware especial chamado "Botão do simulador de dor" para conseguir isso.
Essa cena específica do ROTJ à qual você se vinculou foi expandida no livro EU / Legends " Contos do Palácio de Jabba " novelette " Um Sentimento Mau: O Conto de EV-9D9 "Judith e Garfield Reeves-Stevens.
Ignoring for the moment the Gamorrean guard and the new prisoners {{of course, those prisoners were R2-D2 and C-3PO - DVK's note}}, Ninedenine racked up the gain on her internal receptors, savoring the intensity of it all. She concentrated her meta-analytical functions on the high-frequency carrier wave generated by the pain-simulator button newly connected to the GNK’s central circuits. That signal was … delicious.
Simply put, and Ninedenine did cherish simplicity, she knew that what she did was an act of creation—an art form. Though trying to explain to an organic that a droid such as she could appreciate art was like trying to explain that a droid could feel pain.
Droids could feel pain, of course. One of the two new prisoners coming her way was proof of that—a golden protocol droid from the looks of it, buffed to a courtly gleam, completely out of place in this warren of dank tunnels, decaying power conduits, and scurrying, fur-covered, organic scavengers.
O texto explica ainda por que ela estava certa de que o C-3PO poderia sentir dor:
“Disintegrated …?” the golden droid repeated, trying to make sense of what was going on. Ninedenine wondered if it too had picked up the pain transmission from the dismembered droid, and was experiencing the first touch of disturbance. Pain-simulator buttons were supposedly restricted technology, typically installed only in those droids who had to interact with organics at the most personal level. Strike a protocol droid on the head, for instance, and it would respond that the blow had hurt. Such empathy toward potentially damaging physical sensation was supposed to give them deeper understanding of organics. But as far as Ninedenine was concerned, it just made protocol droids better subjects for her experiments.
