King Louis XVI was condemned to death by a majority of only 1 vote. Amongst those who voted in favor of the execution was the king's own cousin, Philippe Égalité, whom the king did not have positive relations with. Philippe himself would be guillotined on the same scaffold a year later.
There's a lesson here, but it seems most people haven't learned it.
Most people are simply bloodthirsty and have no understanding of Tao.
They have been killing "bad people" for tens of thousands of years, maybe even for millions of years.
So by simple natural selection, bad people should have disappeared or be greatly reduced in number long time ago, because most people make such great effort to kill them.
Yet today, we somehow have plenty of bad people.
Its because those who kill bad people tend to be bad themselves.
Lets face it, Hitler was bad, but that doesnt make Stalin or Mao good.
Its just bad guys fighting bad guys for our whole history and pretending its "good vs evil".
Nothing is achieved by killing one bad guy because you just make room for another bad guy to thrive.
One bad government replaces another.
One bad leader replaces another.
The point is to reduce evil, but people want "easy solutions".
Killing "bad guys" is easy, but it doesnt work because there is no good guys to replace them.
System doesnt focus on creating good guys.
Imagine if government took effort to make sure all young people become good. In just 50 years, crime would be almost completely eradicated because new generations wouldnt be criminals.
But government only focuses on punishments once crime already happens and once person has already become evil. At that point, its too late.
Now, maybe future will enable AI to raise people in a way which makes them completely good, because the current system is failing badly at producing even decent people.
