You can’t force niceness in them, just because it’s a law or rule.  And you can’t take foolishness out of someone… Proverbs 27:22.

In 2 Corinthians 10:12, Paul says no one is wise, when measured by each other.

We are bare before You, O God.  The axe is laid to the root of the trees, every tree that brings not forth good fruit is hewn down & cast into the fire (Luke 3:9).  Forgive those who did evil to us for such as them and us You died.
