Sorry to say, but there is NO EXCUSING what MLB, The Players and the media (can you spell ESPN) the allowance of steroids in the game.
First and worst is the influence these people have on aspiring young players who begin to believe they have to use to compete.
Second is the joke it made of the game and it's history.
Third is the apparent diminishing of the accomplishments of clean players playing now who were pretty **** good players but are generally ignored because their numbers are not as ridiculous as thsoe as the cheaters. Yes, cheaters within or without the law.
