Forgive me for being blunt here but I wonder why people get surprised that this happens and say they cannot understand the motivation behind it. These things never shock or surprise me because it is really a logical extension of humans who are put under stress with no support systems. Follow me over the flip..
So here we have a guy who was on meds, which means he was probably suffering from depression as that is the most common issue. In the USA we drug, not deal with problems, so he gets tired of being a zombie gets off his meds and has no mechanism to deal with the overwhelming issues of the world or his own emotional upheaval. Now, how many people do you REALLY know at any educational facility? He probably did not know on a deep personal level anyone that he shot at, because being doped up on meds makes it hard to connect. So he is faced with dealing with a crushing darkness, decides we are all going to die anyway, says fuck it and kills people he really doesn’t know. This is not hard to imagine. People get shocked but then forget we have troops in Iraq “trained” to do the same thing. You aren’t trained to kill strangers. You are trained how to shoot a gun, but killing people you don’t know doesn’t take all that much if you are depressed.
Remember, killing is a base instinct we are conditioned to repress to have a functioning society. The societies that have the least amount of killing in them are the societies that support a communal living environment, make life easier for their members and stress cooperation, not competition. The USA is all about competition and who cares about the other guy as long as you come out on top. It is not that hard to see how people could easily kill each other after prolonged exposure to that kind of thinking. Look at business lingo, “We made a killing on that product!” “Let’s smash the competiton”, “Hostile takeover” etc etc etc. In schools kids are not taught how to work together, it is all about getting the highest test scores etc. So the USA is a society that is rewarding predatory behavior, in the wild, the best, toughest etc. are the ones that survive. Even in colony behavior with ants, all the ants in a colony may work together but they will destroy any other colony they come across.
So we are pretty much doing this to ourselves, there is no reason to be shocked by it or surprised or wonder how it could happen here. All we do as a country is ignore real problems, cover them with meds, pretty pics and celebrities, never address anything and then act surprised when the results of our actions are detrimental. It is how the USA has always been. These kids/young adults killing people are the end product of our ideals as a country.
Face it, we created them.
