Why aren’t steroid users elected for Hall of Fame?

Certain Hall of Famers believe that users of steroids must never be elected for their club. They affirm that such baseball players, as Sammy Sosa, Barry Bonds and Roger Clemens should be kept out of the Baseball Hall of Fame. They are very happy that these sportspersons didn’t get needed percentage of voting to be in the Hall of Fame. According to them, it is correct. They believe that otherwise our kids get confused. They will believe that they are permitted to administer anabolic steroids and whatever they desire and remain unpunished. So, it would be a negative example for future generations. Al Kaline, Goose Gossage and several others who belong to the Baseball Hall of Fame have this opinion. They even point at cycling, as a good example to follow.
What occurred actually in the world of cycling? The successful American cyclist was accused of taking prohibited preparations. As a result, he was deprived of his 7 Tour de France titles and sentenced to life-time suspension.
Thus, certain Hall of Famers affirm that cycling is a good example for baseball. Baseball players who are found guilty of doping should be banned from this sport totally. Record books must not include information about success of those that have been caught administering forbidden medicines. Those that have cheated should be punished appropriately.
Nonetheless, not every member of the Baseball Hall of Fame has similar opinion. For example, Juan Marichal supports Barry Bonds, Sammy Sosa, Mark McGwire, Roger Clemens, etc. He thinks that these baseball players should be elected for the Hall of Fame. These athletes are stars in baseball. Nobody could prove that they have actually taken doping products. Since there is no any proof, suspicions cost nothing.
Under rules related to voting for the Hall of Fame, baseball players that have amazing skills and those that have contributed to their teams evidentially should be elected for the Hall of Fame.  Nobody doubts that Sammy Sosa, Barry Bonds and Roger Clemens were great players. They made evident contributions to their teams. That’s why they should be in the Hall of Fame.
