Why aren’t consumers of steroids allowed to be in Hall of Fame?

Several members of the Baseball Hall of Fame think that users of steroids must never be in their club. They asssert that such baseball players, as Sammy Sosa, Barry Bonds and Roger Clemens don’t deserve to be in the Baseball Hall of Fame. They are very pleased that these persons didn’t get needed percentage of voting to be in the Hall of Fame. According to them, it is fair. They allege that otherwise our children will be in confusion. They will suggest that they are allowed to use anabolic steroids and whatever they desire and remain unpunished. So, it would be a bad example for future generations. Al Kaline, Goose Gossage and certain others that belong to the Baseball Hall of Fame have this point of view. 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 applying forbidden medications. As a result, he was deprived of his 7 Tour de France titles and sentenced to life-time ban.
So, certain Hall of Famers say that cycling is a good example for baseball. Baseball players that are found guilty of doping should be banned from this sport entirely. Record books must not include information about success of those that have been caught using prohibited substances. Those that have cheated should be punished appropriately.
Nevertheless, not each member of the Baseball Hall of Fame has similar point of view. For example, Juan Marichal supports Barry Bonds, Sammy Sosa, Mark McGwire, Roger Clemens, etc. He notes that these baseball players should be elected for the Hall of Fame. These players are stars in baseball. No one could prove that they have actually taken performance-enhancing drugs. Since there is no any proof, suspicions mean nothing.
Under rules related to voting for the Hall of Fame, baseball players that have amazing abilities and those that have contributed to their teams substantially should be elected for the Hall of Fame.  No one 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 elected for the Hall of Fame.
