God's judgement is not like man’s judgement. Man judges base on what he says at the moment but God is not hasty in delivering judgement. God knows what tomorrow will hold. The person which we are condemning at the moment might be the person who will will a whole nation for Christ in 10 years to come. The man who is deceiving people today might be the one who will teach multitudes the doctrines of Jesus Christ in a few years to come. So, we should not be hasty in our judgement. We should wait for God.
The Lord Jesus Christ said that we should not be fast to judge others so that we won't be judged. We should allow God to be the one who judgement the sinners. God's judgement is perfect and right. He does not make mistakes. We should allow him to be the one who judges those who are defaulting in His commandments.
