What alone can reform the deepest-stained villain?

Never point the finger of scorn toward the erring, but encircle them with your sympathy and love and tenderly exhort them to reform. 

Kindness alone can effect the reformation of the deepest-stained villain. 

Harsh measures towards those who have sinned can accomplish nothing towards refining their brutal nature. Those who spurn the unfortunate—or the criminal, can never progress while that feeling exists. 

Always bear that thought in mind.
