Well put. You exercise righteous judgment, which is not forbidden nor condemned in scripture. You point out the malevolent heart that deceives, and that is what we're suppose to do. The Saint Apostle Paul's letter to the churches in Corinth. The Book of
1st Corinthians chapter 5:12 What business is it of mine to
judge those outside
the church? Are you not to judge those inside?
Be aware too that malevolent hearts can also be due to our encountering a child, chronological age not withstanding. Children lash out and are amused when their behaviors are thought to bring harm to others.
The Saint Apostle Paul's words are wise and apply to any age.
