I had a missing father, and I haven’t done a mass shooting.
Yet.
I am sure it is NOT “automatic” that a male growing up absent their father is “sure” to become a “mass killer” or even a criminal.
I think what is clear psychologically and socially is that growing up without a dad presents a risk factor that can jeopardize a boys maturation process.
I think the mass killers likely have some other familial, social and psychological attributes in common, besides growing up without a dad, but I’m also guessing that those factors can stem from - the causes behind - why they grew up without a dad.
Yet, yes, MILLIONS of good young men, likely the majority of young men who grew up without a dad, managed the shoals of a fatherless upbringing and matured in a good way. There are no assurances, but yes, being fatherless is a risk factor.
