Jesus often judged the behavior of other people during His ministry on earth. In fact, in the end,
He will judge all behavior of every person (Acts 10:42, Matthew 25, etc...).
NO, every judge in the world doesn't need to step down immediately and societies do not need to rapidly deteriorate into lawless chaos with every criminal immediately freed and allowed to do whatever they want (including murder, assault, extortion, robbery, organized crime, etc...) because no one has the right to judge another.
Read Romans 13 and
learn what it actually means. It's Biblical that earthly judges implement a godly rule of law and judge those who break it (note: this is not to be confused with governments wrongly implementing ungodly laws).
In Mathew 7:1-5, Jesus taught not to judge at all if we judge others the way the Pharisees did in failing to remove our own blindness beforehand.
Read 1 Corinthians 5:12-13 with regard to judging people in the church. Inside the church, we judge those who grossly violate God's moral law (1 Corinthians 5) in our midst. We don't do this as the Pharisees did, we do examine ourselves and deal with our own hearts and lives beforehand and we do follow the Biblical model for it (see
https://bible.org/article/church-discipline ).
The historical background of the Corinthian church is interesting. It has long been recognized by Biblical historical scholars that many of the problems Paul addresses in the church at Corinth are grounded in their wrong thinking (that was a result of the Hellenism and mystical cults that had spread across the Roman Empire from the East which many of the gentile believers had followed before becoming Christians).
You see Plato had taught that the body was the tomb of the soul; that death brought liberation from physical captivity; that already in this life one could transcend the negative arena of matter by a higher knowledge of ultimate reality. Various Hellenistic cults offered immortality via union with the god or gods, sometimes symbolized or achieved through cultic prostitution.
Within such a religious philosophical climate, Paul’s teaching regarding freedom “in Christ” and life “in the Spirit” was all too often, and particularly at Corinth, perverted into an enthusiastic libertinism that rejected moral restraints, particularly in the realm of the physical.
The proper response, both to the intolerable case of sexual immorality as well as to their imagined philosophical superiorities, should have been mourning. A repentant attitude would inevitably lead to the removal of the gross immoral offender from their church and fellowship.
That some form of excommunication is intended is clear not only from 1 Corinthians 5:2, but from the Passover analogy in 1 Corinthians 5:6–8 (“Get rid of the old yeast”) and the citation of Deuteronomy 17:7 (“Expel the wicked man from among you”—1 Cor 5:13). The nature of the removal is expressed in the ambiguous phrase “hand this man over to Satan.” Its purpose is twofold: (1) that his “sinful nature” or “flesh” would be destroyed and (2) that his “spirit” would be saved (1 Cor 5:5).
However, the phrase “hand over to Satan” must be recognized in some figurative metaphorical sense as a person literally abandoned to Satan would seem to be lost irrevocably and this end is not envisioned.
The ancient Corinthians had the same problem many who profess to believe in God do today: wrong thinking rooted in ignorance, rebellion, and immersion in an increasingly immoral society.

What Did Jesus Mean by "Judge Not"? | PARSE
We are all sinners. If I was saying that I wouldn't use Apple because Tim Cook is a sinner then I'd be doing the very things Jesus Christ said not to which is judge others and not forgive their trespasses. I cannot however use Apple in good conscience knowing that Tim Cook is advocating that being homosexual is a gift of GOD when it is an abomination, and his company stands behind him on his belief.
