Huck lies to and deceives other characters. Identify several examples from the novel.
Discuss the reasons behind Huck’s behavior and whether you think his behavior is justified given the circumstances.
As you say, Huck does lie to and deceive people a lot in this book, but it is generally for a good reason.
Let me mention three instances. First, he tricks (or at least tries to trick) the lady into believing he is a girl. But all he's trying to do is to get information without anyone catching him and making him go back to "civilization."
Second, he lies to the ferry captain about his family being on the riverboat. But he was only doing that so the captain would try to go save the criminals on the Walter Scott.
Finally, he lies to the King and Duke about who stole the money. But he does that to help out the family that the King and Duke are trying to rip off.
