Reminds me of the idiots that play shooting at each other with BB guns. Airsoft uses soft pellets but BB guns, those actually go under the skin.

Then when they get infections, they gripe wondering how it happened. People never learn, do they?

In the story they saw an entire place wiped out because of the plague spreading like that, so that everyone fled, fought each other, or died of disease, all because of some idiot not cleaning the knife on their little robot.
