At first, Jim is just a slave, someone to tease. As they spend more time together, Huck comes to see Jim as a man. Jim helps him, talks to him, shares thoughts and ideas, and even risks a lot for Huck. The transformation takes time, though, as Huck continues to consider his "sin" of stealing a slave. But he finds that Jim is like a father to him--indeed, even better than his own father. This realization leads him to turn away from what "civilization" says is the right thing to do and to choose hell over turning Jim in. Eventually he turns completely away from civilization, which he believes is not at all civil.
