Wolf, who said that one must be free of sin? If that were true no one would ever be able to give tochacha. (Kohelet 7:20). the Torah does not give such mitzvot.
Avi,
I didn’t mean totally free from sin. That’s why I said “in any particular matter.” It would be hypocritical for a mechallel Shabbos like me to rebuke someone else on the violation of Shabbos prohibitions. On the other hand, were I not such an introvert, I might feel more comfortable rebuking someone for talking in shul since I’m very scrupulous about that.
