He is a liar, a cheater, and a destroyer of lives. The number of journalists, fellow cyclists, and even true sportsmen and gentlemen like Greg LeMond (first and only American to win the tour) whom he had threatened and ruined financially through the major companies and publications that sponsored him will never be known. He used his celebrity and "hero" status to crush anyone who dared to question his cleanness. But make no mistake, the entire time he was a liar, a cheater, and a destroyer of lives.
Yes, he was a phenomenal athlete with or without drugs. But no, he is not "the MAN!" or "one hell of a man and a great human."
EDIT: Actually, Greg LeMond said it best: "I just think he's not a good person and that's all I can say. I mean, he's a facade, if you knew the real Lance Armstrong that I know. I think he fronts himself as a guy who is loving and caring. From my experience, he's not a nice guy and I've had some very difficult periods with him. And I don't believe he'll finish up having any friends in cycling."
