Pap was hardly a parent. If anything, Pap orphaned his boy. When Pap realized he could get something out of Huck, he took custody and abused him. When Pap shows up the two had been estranged for years. I think Huck questions many society’s values as a result of his relationship with pap. At one point a magistrate was willing to let Pap have Huck under his Pap's custody even though Pap's motives were clearly for Huck's money. Huck's relationship with Pap is the antithesis of any kind of “ideal" father / son bond.
