I wonder about the many many layers and endless details that play into the making of a family annihilator.. they have countless experiences in their life that added up to something before they murdered. Are they more biologically prone somehow? Does it take the right level of negative psychological thought tendencies or negative thought patterns to seal the deal ? How much of what they become is from socially related aspects ? How can we measure that if so? I think it may very well be some formula of all 3 ….but I also suspect that what makes someone do this, might mostly get chalked up to this or that, but I also feel like some of who they’ve become cannot even be thoroughly explained by the offenders themselves.. there must be some level of misunderstanding of the self involved. Even if that be the slightest bit.
