Why?

 Okay, 

    So I have a fascination with all things having to do with killers. Serial killers, People who commit massacres all of that. I used to want to go into prisons and work with people who committed those random acts of violence and try to find out what it is that drives a person to "snap". I mean come on we've all had that time where we've thought "Wow, I really wish I had a gun so I could just go nuts on this person or people". Now most of us never act on the impulses but what about the people who do? What happened? If you talk to the friends, family or coworkers of people who committed such crimes you'll hardly ever hear "Yeah, they were weird. We all knew it was just a matter of time." No, usually they say something like this. "(blank) seemed normal and friendly we never saw this coming." They can't all be mental health issues, yes some are, but most of the time the killers never had a record of mental instability. So why? Why do some people just "snap"? Is there really a breaking point in the human psyche where all rational thought is tossed out the window and your driven only by animal instinct? 

  Most people when they hear about a tragedy, like for instance that story in the news recently where a man shot his wife, two children and then himself, they tend to think "that's too bad" or "How disgusting what a coward" or whatever. My first thought is, "How did he get there?" How did he reach the point where his only thought was, "I have to kill my family and then myself, that's the only way everything can work." How does a person reach such a low point that all they can think about is to harm themselves and others. But my main question is why? Why are they different? Lost of people have reached the lowest of lows and never pulled a gun on anyone. So why is it these people do? Was it how they were raised? Is it some sort of violence gene that gets passed down? Did they eat something that when its mixed with anger it turns violent? What the heck happens? I don't believe its evil, I don't think that evil just got to that person. I think its something more, I think its something that we may even be able to pin point at an early stage. 

  Like when you were in elementary school, did you have the "weird" kid? Did you and your friends ever say to each other "He/she is going to prison someday." At my school we had a kid like that, he used to pick up bugs and pull their legs off one by one and laugh. Obviously people like are not mentally healthy, but did you ever stop to wonder maybe the little blonde haired, blue eyed boy who everyone loves is really the one to worry about? You just never know who could possibly have violent tendencies. But again, why? WHY do they have those violent tendencies? 

I've just always wanted to know.
