When He created the world, He created two ways to repair everything: with harshness or with compassion. With a slap or with a caress. With darkness or with light.
And He looked at the light and saw that it was good. Darkness and harsh words may be necessary. But He never called them good.
Even if you correct another person with harsh words, God takes no pleasure in it. When He sees His creatures healing one another with compassion and kindness, that is when His smile shines upon us.
