While I understand the desire to draw a big conspiracy theory around Guiliani, but I think he actually started out as someone with a massive ego and the intention to do good. Going after the Cosa Nostra in the 80s took serious guts. He also went after Wall Street in a very public way that sent some people to jail. His term as Mayor of NYC was controversial and there is a lot to criticize, but he was still taking big swings trying to make change.

If he had stayed a prosecutor, he'd probably be a much more admirable person. But fame seems to have been his driving ambition since 9/11.
