Oh, you're asking why humanity is entrenched in such barbarism worldwide?
That's simple: High prevalence of low IQ groups, and terrible parenting resulting in widespread child abuse/trauma.
High IQ is necessary, but not sufficient for an advanced, peaceful society.
The high IQ group has the mental horsepower to create complex, efficient, reliable machinery which underlies and supports an advanced civilization.
For that utopia to come into existence, the high IQ population needs to deliver a bunch of children to adulthood, without trauma, into a largely voluntary society where collaboration is rewarded, and coersion shunned.
The research I have seen shows that countries whose population has an average IQ of 90 or less fail to create or maintain democracies (not that democracy is great... but the people having some say is generally better than the autocratic options)

Sadly, bad parenting is very common, which is shown to lower IQ and leave children with sometimes life long trauma, which certainly effects their life outcomes.
And here's a free book which I think offers a lot of useful perspective:

The best thing we can all do at this time is help out abuse victims, try to make the abusers see the errors of their ways and want to change, and become peaceful parents ourselves.
That's the way I see it. The goal is less violence, more voluntarism & negotiating between individuals.
