The point I'm making, and you are missing, is that guns not only facilitate, but encourage violence. Guns are the "tool" (your word) of choice for criminals, thugs and angry assholes with an axe to grind against society.
It doesn't take a genius or a sociologist to understand that there are underlying social problems that cause the violent urges to begin with, not to mention the innate violent nature of humans in general. But when you take those factors, add them together and throw an over availability of guns into the mix, what you get is what we see today... weekly mass shootings in which innocent people, small children included, are mowed down and slaughtered because some unstable nutjob was able to easily obtain access to as many firearms as they wanted and enough ammo to wipe out an entire football stadium of people.
The reason why we're stuck in this never ending and increasingly escalating cycle of violence, is because conservative males are scared to death that if their guns were to disappear, their imaginary manhood would disappear right along with them.
