As long as guns have existed, they have been occasionally used to kill innocent people. The same is true of knives and bludgeons and myriad other forms of weaponry. As long as human nature remains to a great degree unregenerate - evil - what some people, in pursuit of their own ends, are willing to have other people suffer - some people will have the disposition to do harm to others and, notwithstanding any written law, will find the means to get the job done.
To state the obvious, unregenerate human nature is lawless. Passing laws to keep weapons out of the hands of the lawless is transcendently stupid. Apart from being practically impossible, presuming to solve the violence problem - and it is more correctly labeled a violence problem than a gun problem - by removing the means to do such violence, rather than addressing the motivational aspects of it, obviously misses the point, is the height of stupidity and will come to nothing. Though such an approach - trying to take weapons away from everybody - does appear to serve the superficial, reactive need of the mindless to "DO SOMETHING!" and has the added benefit of virtue signaling for those who advocate it, it cannot possibly solve the societal problems caused by unregenerate human nature - human evil.
The unassailable, non-negotiable reason firearms shall never be taken from the hands of law-abiding citizens boils down to two fundamental, deeply-rooted realities - natural laws - one being the absolute right to defend one's own person - and, by extension, those under one's own roof - from violence that might be inflicted by others, and the other being the absolute, God-given right to defend one's liberty against those who might wish to take it away. Free societies - especially the American society - are built on these two essential foundation stones. Remove either one, and people are no longer free.
Though it is admittedly a hard doctrine, beyond the grasp of the intellectually, morally and spiritually effete and invertebrate - especially, when we are occasionally confronted with murderous evil like Uvalde that costs the lives of innocent people - an evil, by the way, that could have been truncated if there had been guns in the hands of good guys already in that school or early on the scene - there always has been and always will be a price to pay in blood for keeping in the hands of the people the power to use deadly force to protect themselves and their liberty.
In an increasingly degenerate world, where freedom, individual and collective, is relentlessly under assault, this is a price we must always be willing to pay if we are to remain a free people and nation.
