I’m looking for a movie from the 80s that has a robot that had a hole drilled in its head, the only way the humans could tell if he was the good one. It had a replica that killed one of their friends and the robot said”at least she didn’t die in vein”. I think it was gold in color

I Houghton that at first but unfortunately it’s not. It begins with two young men who have clear like masks on to disguise themselves to these androids. It’s a group of humans that are a rebellion of a sort. They have this little android that he shuts down to keep him from getting hurt, then the enemy drills a hole in his head to clone him and the cloned android infiltrates and kills one of the girls.
