It is a shame we cannot control ourselves -- humans, that is.
My own thoughts are that society has evolved into this riotous lifestyle over many, many years. There is a real difference with the discipline, values, work ethics, family structures that have evolved over the past 100 years. The communication, transportation and with that the media access which we now either enjoy or are subjected to, have all made things available in a way never known before. Plus, drugs were not so prevalent as now, although there were such drugs/weeds in use. Money, housing needs were not the same although just as critical as because it is all relates to the times and values of people and money, etc.
I believe we should be able to own guns. Personally, I have several -- rarely used but, here and had for so long there is no registry for them that would alert anyone I have them. Their use is certainly controlled as is their safekeeping.
So, having watched a lot of westerns when TV became a reality, it is a fact that many crimes were committed then for all the same reasons.......at least for the wrong reasons. Since the communication was not so great in Civil War times and forward, much of the gun abuse is just not considered or known widely. But, there were situations just as ugly then. Gun control wasn't even considered.
We know many countries had civil wars, the severity was less as the available components were less.

Awareness plays into the whole mess -- guns & world disruptions -- via our multi-media outlets. Those are my thoughts -- no resolve, just some overall "why" input.
