The game's story is quite fucked up from the puppets' perspective
So they are essentially born as this slave race, some may even get their ego awoken, but can't live according to their own will because of these rules branded onto their souls. Then the Puppet King has them slaughter the infected to stop the plague, but their former masters see it as a slave rebellion and hunt them by the thousands. They get the upper hand, but someone defeats the one who commanded them and they all lose hope, without any direction or guidance. Then the infected, the ones they just managed to keep at bay start spreading like crazy, killing them, taking over their bodies! I just hope they do experience some sort of death when their bodies are broken, because I can't imagine a fate worse than being locked in this shell of your body, all your limbs broken, and a mass of tendrils moving them however they please, slaughtering the people you've tried to save.
