The documentary tries to uncover the underlying reasons that he became a homicidal bomber, his dislike of technology and those at the forefront of it, be it academia, major airlines, computer science, etc. The truth is, no one really knows. He doesn't give interviews, other than this one, although his family did, he is deeply uncomfortable being around women and other people, and I would say his advanced mathematical intellect vaulted him ahead of his peers and made him even more isolated as a child. Being subjected to some three year long, bizarre psychological experiment at Harvard when he was only a teenager likely set the hook for life. Interesting they were interviewing a former warden at Florence Supermax, and he said you could not create someone better suited for life there than Ted.
