Rigor Versus Kindness
Rabbi Nachman Horodenker said: "There are two ways of curing offenders. Some claim a cure by inflicting privations, but these usually result in the transgressor becoming embittered against society, and cruel henceforth. Others effect a cure through persuasions which oftentimes transforms the sinner into a man of kindness and helpfulness."
