You sound like a Dr. I once knew...
Matthew 7:3-5 And why behold you the speck that is in your brother's eye, but consider not the beam that is in your own eye? Or how will you say to your brother, Let me pull the speck out of your eye; and, behold, a beam is in your own eye? You hypocrite, first cast out the beam out of your own eye; and then shall you see clearly to cast out the speck out of your brother's eye.
In context, we are to cast the speck out of our brothers eye which requires judgment. However, we are not to condem another through that judgment and we are definatly not to cover our own sin through sombody elses sin.
Peace :D
