Ivy, I don't think anybody fakes cancer. That he recovered so quickly and then won several Tour de Frances after that pretty much convinced me that he was taking some kind of PEDs. It really didn't and doesn't bother me that much though because I assume that so many top athletes have taken them. There was a great running back in Chicago - Walter Peyton. He died in his early 40s from bile duct cancer, which is highly likely related to Steroid use when he was a player. He almost never missed a game and could always be counted to make the play when it counted. He is revered as the greatest running back to play for the Chicago Bears in the last 40 years - one of the best of all time. People gloss over the steroids part it because they all did it back then. Also, he was friendly, mischievous and smiled a lot. People liked him.
It's easy to judge people and the Armstrong has pretty much been crucified. You can see it all piling on - the tyrant, the psychopath, the abusive brute who destroyed people. Really? Lance Armstrong doesn't come across as the most friendly guy. He seems arrogant and doesn't smile. He strikes me as an INTJ Enneagram 8 - not the most sympathetic character in the world and certainly not the most charming in his apologies on national public TV. He came across in the interview as cold and mostly unemotional. It does color your judgment. I wonder how well the interview would have been perceived if he was an ENFP Enneagram 7.
He took PEDs like a whole lot of people did and he got caught. His punishment is that he can't compete in any sanctioned athletic competition permanently. Seems like enough to me. For he people he "disappointed" or "let down" - I'd say get a life. He was a professional athlete not your friend. He did survive an advanced form of testicular cancer and he did manage to compete on the national stage after that. It's an inspiring story whether or not he did drugs.
