I love that moment when he's talking to Lewis and says he can feel his family but can't remember them and that he just wants to be alone. Robocop is still trying to reconcile his state of being. Taking off the helmet to reveal his human face is a moment of acceptance. When he touches his face with his robotic hands that's a machine's moment of ultimate self awareness. Just consider the head trip he's going through. It's Robocop meeting Alex Murphy for the first time, this man he knows intimately because he has all of Murphy's memories and life inside him. Imagine it like this: you go about your life and start realizing you were actually someone else and something horrible happened to that person, are you really the person you used to be or are you the person you've been living as? I find Robocop emotionally powerful not because it's Murphy realizing what's happened to him, but instead it's Robocop realizing he was Murphy and takes immense compassion for what has happened to Murphy and thus himself. It's a complexity in both science fiction concepts and emotions that I feel simplifying it to being just a man in a robot suit does a disservice to. The machine, in seeking justice for the wronged human, is more compassionate, and more human, than the humans that built him in the first place.
I don't see Robocop as a movie about humanity triumphing over the machine. ED-209 and Robocop are still both robots at their core. But it's through the shared experiences of a human being that the machine demonstrates what it means to be human more than the humans do. When Robocop puts an end to the proceedings by stating his name is Murphy and exiting stage right, he's declaring his name for the first time, not just reasserting an old one. He's not a product, he's a living, self aware person with agency, and he's made a choice about who he is and wants to be. That's infinitely more powerful to me than just "I'm really Alex Murphy guys!" That's why the movie can end there without a denouement. It's a huge statement about how incredibly far he's come as a character.
Of course all this requires you to really consider what the hell Robocop is through throw away lines and suggestions in the movie. You know, think about it. But that's why Robocop works so damn well as a movie in the first place. The story does work just fine as being about a guy who wakes up in a robot suit and takes his life back. I just think that's like saying The Odyssey is about a guy who gets lost at sea. Sure that works but that's not the full text of the matter. And Robocop is a movie with a lot of text and subtext and, given what's happened in real life, meta text. I find it strangely ironic that Robocop IS the reality we live in now, with rampant consumerism, talking heads media personalities run rampant, grossly inhumane corporate entities, and a Detroit that is almost exactly like Detroit in the movie, but we need to update it to make it more relevant for modern times. It seems to me that while Robocop may be able to rise above his role as company product, his movies cannot.
