The damage done is not so much a product of the crime itself, but the doubt that it casts upon the entire sport. It goes to show that there isn't much integrity left in the sporting world. The rule seems to be "Well, everyone else is doing it." Like our moms said, "If your friends jumped off a bridge, does that mean you should?"
These guys dope to keep up with other dopers and not get left in the dust. How they could not see the eventual outcome is tragic.
