Twain satirizes do-gooders--more politely known as philanthropists--in his description of the extravagant, tearful sentimentality displayed by the new judge and his wife in their attempts to reform Pap Finn. For instance, when Pap solemnly gives them his hand to shake, the judge's wife is not content with just doing that, she also kisses his hand. Twain plays up the complacency, not to say pomposity, of people like this judge who appears confident not just of reforming Pap but doing so literally overnight. He gets a rude awakening when Pap repays all his efforts by getting hopelessly drunk, climbing out of the house and falling and breaking his arm. Therefore Twain shows just how useless do-gooders can be. In this instance, the judge is completely taken in by mere appearances, when Pap seems to be so ashamed and repentant, making a long solemn speech about how he's going to turn over a new leaf. His actions don't even begin to correlate with his words, however.

Twain often took 'do-gooders' to task in his writings--members of temperance societies, prison reformers, and the like. He shows them as being often exaggeratedly sentimental and affected, and hopelessly unrealistic in their expectations of bettering individuals and society.
