I want to know how Dzhokhar Tsarnaev went from popular, easy going high school student

15. it might be a kind of culturally reinforced version of the "Dependent Personality Disorder"

I can remember when I was a certain age - I could have become so enthralled with someone and so convinced that they were the be all and end all - they could have talked me into almost anything. In this case there might have been an even stronger cultural tradition of a younger brother really looking up to an older brother.

I know when I have read of serial killers or other heinous crimes that involved more than one perpetrator - it appears to be a common pattern that one leads the way and another one - who many times would have never on their own thought of committing such crimes - through some dynamic of emotional dependency surrenders their will to the dominance of the instigator.

I doubt that Dzhokhar would have ever on their own even considered doing such things. For that matter - what was Tamerlan thinking? Boston is not in Russia. The U.S. government and media has generally expressed sympathy for Chechnya. So far we don't know of any evidence that he had any foreign accomplices. What could he have possibly imagined that he could have accomplished?
