Consider: living weapons who are abandonware.
they were too unstable, too sensitive, too rebellious, and since they weren't worth the effort/resources, they were discarded.
living weapons who were disabled/mentally ill/neurodivergent before becoming weapons, and who were decommissioned due to their ""flaws"".
a living weapon trained as a young child, later adopted into a safe home away from the war. by now they know they're safe, but some of their conditioning remains.
bonus points if they repressed it for most of their life and now that they're safe, the memories come flooding back.
living weapons who miss being weapons (the training, the injuries, the punishments, their handlers) because it gave them a purpose.
"Please, just give me a second chance. I can fix myself. I'll be good this time."
living weapons searching for handlers who are now long gone.
"I can fix myself"... living weapons that feel lost without orders and feel like the aimless lack of direction is some punishment due to their condition... "I can fix it (I can be a heartless killing machine again) if you only give me the chance. Please." Augh 🙏 Fantastic
