In my VERY humble opinion, this woman was/is not evil. Her mental illness was not even examined a little bit in this piece. Which for me at least, left a gaping hole. One or two interviews with mental health professionals to explain this "phenomenon" would have been helpful.
Also -- more fingers should have been pointed at journalists early on not doing their jobs. As a life-long (now retired) journalist, one or two phone calls early on would have exposed her lies early on. Did no one think to verify what hospital reattached her arm, or verified her Harvard degree, or her employment with Merrill Lynch? Wow...somebody was really asleep at the wheel.
