Huck's independence from his father "Pap" enables him to be a model of rectitude. Pap's inebriated state and selfishness have an adverse impact on Huck. Not only is Huck forced to fake his death, but this horrific experience also traumatize Huck. In the events that Huck and Jim continue their journey towards free states, there are times that they steal food from the nearby towns. His rationale is what his father has taught him, "Pap always said it warn't no harm to borrow things, if you was meaning to pay them back, sometime; but the widow said it warn't anything but a soft name for stealing" (77). Juxtaposing stealing to slavery, Jim is a runaway slave, and he technically stole himself from his master. What Jim did is considered "wrong" in their society, but stealing is not only wrong based on societal issues, it is also morally wrong. Huck is better off without his father. It seems ironic that a father should guide him towards goodness, but Pap's crooked belief makes Huck immoral. Therefore, Huck is a better person when he is not under Pap's care.
Twain brings Huck to the hypocritical Grangerford family to expose how their religious convictions do not ensure goodness. The Grangerfords have good manners toward each other, but the ongoing feud destroyed that. When Huck and Buck are outside walking one day, Buck tried to shoot a member of a Shepherdson family. Huck was startled and asked Buck the reason he attempted to commit murder. Buck explains there is a feud between the Grangerfords and Shepherdsons. When both families went to the Sunday mass, both families acted like everything was normal. Huck's perception of the mass was, "It was pretty ornery preaching- all about brotherly love, and such-like tiresomeness; but everybody said it was a good sermon, and they talked it over going home, and had such a powerful lot to say about faith, and good works" (129).
