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…
Eugenics doesn’t mean killing anyone, just improve the genetic qualities of humans.
You could do selective breeding, incentivized breeding (entice the right candidates with whatever) ,gene manipulations, etc…
