Teach your kids well, to resist the depredations of modern society.
Keep a good enough relationship with them that they can come to you when they have problems. That takes time, and no small amount of giving on your part.
Teach them to resolve problems calmly, rationally, and that is is okay to just walk away at times--a sign of strength, not weakness.
Teach them respect for firearms, but even more importantly, for life.
Especially human life.
And teach them that there is a power far greater than all of this, and He does take an interest and answer prayer (even if sometimes the answer is "no").
Do all that, and you won't have to worry about your kids. Other kids who come to visit should know your rules, too, but if you aren't comfortable with them following them, you can lock up the things they need not mess with. We didn't let kids like that in very often, and not for long.
We were taught to kill nothing for 'fun'. If you aren't going to eat it, and it isn't a threat, leave it alone. if you must kill it, for food or otherwise, do it in such a way it will not suffer.
Human life is sacred, and not to be taken lightly.
But that was in the days when Gas Chambers and Electric Chairs were used to deal with murderers, and prosecutors were unlikely to cut any slack to the worst of offenders. Killing someone could get you dead, not 25-30 years of dragged out appeals.
Psychoactive medication administration has risen in the interim as well, and it seems that many shooting incidents involve either medication or the lack of it, even though prescribed (which disuse (not just the use thereof) can cause some serious mental side effects).
Guns are little different. The rules have changed, the guns haven't much, 30 round magazines for semiautomatic rifless have been around since before WWII (M1 carbine comes to mind). At city ranges they aren't any less lethal and don't shoot slower than their modern counterparts. Semiautomatic pistols are basically the same, too.
While the rules have made gun ownership more difficult to do in some places while remaining in legal compliance, and driven the peaceful and recreational uses of firearms a bit underground in urban areas, crime has gone up.
Not because guns haven't been there, even if in reduced numbers, but because of cultural changes, some of which have made it harder for the law abiding to carry one in case they need it for self-defense. That tilts the playing field towards the criminals, but it also removes something from 'polite' society that once was a normal fixture and renders it exotic, Instead of a firearm being an acceptable means of self-defense, it becomes a desirable offensive means to feeling powerful in a world that increasingly seems to emphasize the marginalization of everything good and decent about our society while touting the behavioural deviants and outliers as 'brave' and 'empowered', leaving normalcy disaffected, while blaming 'normal' people for the shortcomings of individuals and cultural failures of the many.
We were quite a bit better off, culturally, when such deviance was eschewed rather than promoted, and when kids are involved, they are stunned when the real world doesn't react to them like what happens on TV, so instead of introspection, self evaluation, and change, they blame all else for not reacting like they think it should have, just as modern media and society and even the schools teach them. Thus they generalize and hate, without reason, any and all who seem to stand in the way of their pet personal indulgence.
It is a combination of factors which have led society here. Disarming those who might need to resist that violent culmination is a grave error that leads nowhere good.
