I am not even remotely religious. I don't believe in any deities. But the quote about casting the first stone feels applicable here. You better not live in a glass house if you're going to be casting any stones...
I guess with this logic, we shouldn't have any laws or rules that hold people accountable for their bad behavior? Perhaps you should study the context of that quote in a bit more detail.
I don't care whether Rose goes to the MLB Hall of Fame or not. He was a great player, and also a really crappy person for reasons well beyond gambling on games he was personally involved with. I know there are plenty of HOF players and other famous people who are even worse. One of the great flaws our society is that we put some really crappy people on pedestals because they are good at sports or some kind of performing art. It's no secret that there are often unequal standards and outcomes, especially for the rich, athletic, and famous. However, that doesn't mean that we reject any and all standards of behavior because somebody else wasn't punished enough.
