For me “How long could I get away with driving like an ABSOLUTE ASSHOLE all the time before I lost my licence or had an accident.” Speed limits, red lights, stop signs… forget them all. Every day I have to drive sensibly and obey the law because without my licence I dont have a job, and every day I see at least one person driving like an absolute moron and I wonder…
So basically unit 731 stuff
Unit 731 was garbage science. About the only thing worthwhile that came from that was learning how better to treat hypothermia. Most of their experiments boiled down to “If we do terrible things to people, how much will they suffer?” with the answer being “A lot.”
It doesn’t take live experiments to learn things like surgery without anesthesia is less effective, or that not treating people infected with horrible diseases causes them to die in agony.
