According to reformed theology, is hypocrisy a sin?

People don't like hypocrites, and they get a pretty bad rap in the Bible (especially from Jesus), but is hypocrisy itself a sin? In reformed theology at least, every one is fallen and cannot avoid sin, and is by definition a hypocrite if they point out anyone else's sin. It seems to me that hypocrisy is a necessary evil in the process of accountability. The difference I see is in the manner of being hypocritical, Jesus was critical of the prideful hypocrites who could not see the flaws in themselves, but maybe there is a safe way to be both hypocritical and humbly acknowledging your own sin?
