I disagree with the premise. Even at the time of the composition of the Constitution, there had long been the argument of whether people are inherently good or inherently evil.
But the two things somewhat canceled each other out, for there are consistently good people who do evil things and evil people who do good things. But the argument cannot be left in shades of grey. So the question becomes, “What motivates people to do good or evil things?”
The answer they came up with is brilliant. That people are neither *inherently* good or evil, but instead they are *weak*.
So examine our Constitution with that idea in mind. For both the organization of our government as a whole, striving for balance of power, with different bodies of men with different motives; and for our Bill of Rights.
The 2nd Amendment protects the weak from the strong. No matter if the strong imagine themselves as good or evil, in either case they cannot just trod on the weak to achieve their ends.
It truly defeats the idea of “might makes right.”
“We think people, given the choice, would rather be nice to each other. But just in case... Keep a weapon handy just in case you need to end a bad actor.”
Either way, I approve.
