No sense chiding evil doers. They're deaf

No sense chiding evil doers.  They're deaf.
A lump of coal. No mercy. They've run out.
Self-advantage is their only heft.
Their helpfulness is ugly as a pig's snout.
No sense chiding evil doers.  They're deaf.

Such is the heart when it hardens. A black
heap. And cold.  Words alone will not
suffice.  Your most earnest pleading will lack
an ear.  Better to lecture an idiot.
No sense chiding evil doers.  They're deaf.
