Jesus never gave up shaming. He used it Himself. Without the sense of shame, the sense that a person knows they are doing wrong, there can be no recovery and no grace. Shaming is best exhibited by Jewish mothers and Catholic priests.
But Jesus never supplied superfluous shame. Here is where you deny the ability of grace to suggest repentance just by its mere presence and the mere action of conscience.
Jesus said people who do that kind of denying of the power of grace are preceded by prostitutes into the kingdom of heaven.
What are you going to do about THAT shame, shame-boy?
