Answer:
Though both men are criminals in their behavior, the character of the Duke is more superior than the King as he cares about how the money is attained. He opines that he need to earn it while the King doesn't care how it is got as long as he get it for himself.
The character of the King is least likable than the Duke for his contempt and ill treatment of people, thinking of getting money from them by free or cheating but not caring about how he gets it.
Explanation:
Mark Twain "The Adventures of Huckleberry Finn" tells the story of how a young boy's quest for freedom and adventure led him through numerous places and events, both good and bad. The protagonist "Huck Finn' ran away from his captor father to explore and enjoy freedom on his own terms.
The characters of the King and the Duke are two like people, both deceitful and extorting money from innocent people they encounter. But while both men may be of the same pedigree, the role of the Duke is morally superior to that of the King. This is because even though they both want money and extract it from others, their beliefs and ways differ. While the king has no problem attending a religious event but still steal people off their money, the Duke feels the need to 'earn' the money. The King has no problem with however he attains the money while the Duke has some reservations on how he gets the money. This sets them apart in their morality.
The Duke is more likable as he still seems to have some sense of honor in getting money while the King just cares about getting it, irrespective of how it is attained. He doesn't seem to care if he hurt people or not, fleecing them off their money easily. Whereas the Duke cares about how he get the money, stating the need to work for it instead of easily getting it from people freely or by force.
