I don't think it's sad, I find it evolutionarily appropriate. If there's competition, there's drive to win, and in the drive to win, there are temptations to gain an advantage, and where there are ways to get an advantage, they will be used. From my years and years of review, study, and use of PEDs I'm simply in awe of the dedication to cheating that is endemic in cycling. It's quite fascinating, at least to somebody with no qualms about integrity in that particular sport.
