I liked what @SavoirFaire said and I would like to expound upon it, but without some scientist’s theory, or silly study of four serial killers or whatnot.Too many “theories” and “scientific studies” get ultimately completely dispelled anyway.
I think that people are a combination of nature and nurture, which determines certain key elements in their lives, which ultimately contribute to their general well-being, and dispositions. Plural.
I think there is a correlation between one’s job and one’s nature. Sometimes it works out perfectly, other times there is dissonance and dissatisfaction, leading to frustration. t many different levels. Our work, plus sleep, take up more then ⅔ of our lives.
I think one may have a certain charateristic flaws, for lack of a better term, which may lead them to believe that life is not so precious. They might have a certain flaw – a perversion – which compells them to take lives, and get excited by this – rather than celebrate lives – help lives – like doctors, nurses, paramedics, firefighters, policemen and therapists – et al. This horrible, but unique confluence of events is what causes the rare exception to society – the serial killer.
There might be a perversion – a flaw – which causes them to see life as meaningless, worthless – not worthy of being taught something, as do teachers, councellors, guides et al.
A combination of these horrible factors, plus timing, plus luck – the definition of which is: the meeting of preparation and opportunity – (in this case, passive preparation) may cause a few sociopaths, psychopaths – to snap.
And thus are born the very few, very very few (but celebrated and written about because we love our shock and entertainment) serial killers.
I can tell you that here we haven’t had any thus far. We all serve in the military, for at least three years. I was broken down and made into a killing machine. I am still the same person I was many years ago when this happened: a poet who seeks peace. As are all my friends and everyone I know, including, but not limited to Barak and Netanyahu – former Commandoes, who want nothing more than peace – and would never in their wildest dreams, become anything like a serial killer. Swords into ploughshares. That is our motto and dream. And it shall happen one day, I know it.
Politics aside, please. No-one – not one single ex-commando or infantryman in Israel ever became a serial killer – as there haven’t been any in our history.
So I truly fail to see the correlation between the two: when someone snaps, when there is a confluence of these opportunities and happenstances, the killer will weild his/her poison, wire, knife or gun – and it won’t matter whether they were trained in the military, or sat at home playing video games all day for a living.
