Huck's decision to save Jim

While, I agree that Huck should try to save him, I don't know that his decision was morally correct. Jim is a runaway slave, and while the duke and the dauphin didn't necessarily have the right to sell him, in this situation, he is still someone else's property. While that isn't necessarily right, it is man's law, and we're supposed to obey our superiors on earth. Jim was sold by the duke and the dauphin to a man, who paid for him. Jim is a runaway slave. There's so much legally and some morally wrong with this whole situation that it's harder to say what is right and wrong. I think that in this particular situation, I would have acted as Huck did, but I don't think it was morally correct.
