Huck Finn is a timeless classic that is enjoyed by readers of all ages. Mark Twain manages to convey a theme of compassion and unexpected kindness through the actions of a young adolescent boy who dares to defy his society's primitive and judgmental values.
At the beginning of the story Huck is placed in an okward position when he is sworn to silence about Jim desition to flee from slavery. In Hucks mind he knows that what he is doing is wrong and if anyone found out he would be punished. But at the time Huck wasn't thinking about what would happen to Jim because he didn't see him as an equal. Growing up in a society that thinks of blacks as animal and nothing else Huck didn't seem to care about his soon to be black friend.
The first sign of compassion that Huck expressed is the fact that he stuck with Jim on their trek down the Mississippi. If anyone saw a black man on a raft by himself they would lynch him and Huck knew that.
For the next week or so Jim and Huck spent their time getting to know each other. The longer they were together the closer they got and the more attached Huck became. Huck still saw himself as being better than Jim but as they traveled down the river the further Huck came to breaking through that social train of thought instilled in him by everyone he has ever known. Huck realized that when he decided that he would go to hell for Jim.
Huck saw that Jim was another person and not just some animal put on this earth to do work for white men. I think that Mark Twain was trying to show people that there is more to a person than just the color of there skin. Even growing up in a place that condemned black people Huck was able to over come that.
