Khan wishes to keep the colony safe with as little bloodshed as possible. He also seems to have developed trauma from encountering the Murder Drones, refusing to arm the Worker Defense Force in favor of fortified doors. His pacifist way of thinking clashes with his daughter Uzi's aggressive and forward tactics; upon spotting N, Khan refuses to pick up her railgun, instead shutting the blast doors from her. This trauma is most likely from him having to put his wife 'out of her misery'.
