K2SO didn't understand the significance of death, after all they were only a droid. They knew the meaning of it, but the effect it had on the dead and the living was still a mystery to them. They were able to be reprogrammed and transferred to a new ( though they were still trying to clean out the rust ) model. They had no real reason to fret over themselves, however, they could recall their last moments when they and the two meatbags were under siege on Scarif. It only seemed to be like yesterday yet light years behind them. They remembered the troopers breaking into the control room, searching for them. The smoke from their destruction and chassis. How the world slowed down, allowing them to listen to Cassian’s concerned voice as they destroyed the controls to the room. In their last second, K2 will never forget the simulation of Cassian’s escape. K2′s only hope that the human escaped and lived a long life. He was the only one who ever treated the droid as an equal to another human.
. the droid was alone, busying themselves by scrubbing the inside of their knee joint that they detached from their body. They wouldn't be satisfied until the rust was completely gone. Honestly, humans were such incompetent and fragile beings, no where in his programming did he understand their longevity.
