Huck's moral delima

I read the book The Adventures of Huckleberry Finn by Mark Twain. Slavery and racism played a major role in this book. Jim escaped from his master because he was afraid he'd be shipped down south to work on a plantation which was very hard. He wanted to go to Ohio were his wife and kids were slaves. He was going to free them. On their adventure, Huck and Jim had many encounters with racism. The people in the book used alot of derogatory terms toward black people such as the "N" word. There also were many men who were hunting runaway slaves to make some money. One time to deter some men who were going to capture Jim, Huck pretended he had small pox so they wouldn't come near them. Of course everyone in this book is so racist because it was set over a hundred years ago.
Huck had a lot of revelations about what was right and wrong in the book. It started with when he helped Jim escape down the Mississippi River. At first he didn't want to help because Jim was someone's property, but then he changed his mind because Jim was a human too. The second time Huck's integrity was questioned was when this guy saw them floating down the river. Huck lied to the guy to keep Jim out of trouble. Over time, Huck and Jim became really good friends and they would do just about anything for each other. They overcame racial boundaries that separated them at one time.
