There are certainly a number of contributing factors. We have discussed here the fact that many of the shooters seem to come from single parent homes. Mental illness has also been blamed.
Albert Mohler, the president of Southern Seminary– a Southern Baptist institution– has floated an explanation. He says it is because of a lack of restraint that is increasingly present among the population. He describes an “unraveling” of the moral fiber among Americans; the lack of governmental authority maintaining order; and the impact of social media.
He says we need Christianity. I agree.
But I would specify one ingredient that seems to be increasingly a factor– the lack of conscience. Perhaps we need to discover once again how a good conscience is formed and maintained in children, teens and young adults. I suspect that if we studied and discussed this in an earnest and open manner, things would be handled much differently in our culture.
