Bonds vs. Rose

Should someone who commits a baseball-related criminal offense be allowed in the Hall of Fame? If so, then shouldn't baseball rethink Pete Rose, a player who, in his own right, earned his major baseball achievements honestly, whatever else he might have done to besmirch the game.

Can anyone think of a good reason to suppose that Bonds should be in the Hall of Fame, while Rose should remain out?

One answer, from a student of mine, said that Bonds should be in because he did not break a rule in place at the time.
