Frank, 


     The strongest point of your essay is that you have really dug into the text and
   identified most of the places where Twain shows Huck's "sound heart" overcoming 
   his "deformed conscience."  You have done a very good job tracing how that 
   develops over the course of the story.  You also clearly understand what Twain
   meant by Huck's "deformed conscience" and you explain that well.  

     But I think the opening of your second paragraph "A common misconception ... " would 
   have made for a much more effective opening for the paper as a whole.  What you have 
   at the start of your first paragraph (the interior and exterior journey idea) is 
   somewhat too general and not directly related to your actual topic.  Also in 
   your opening paragraph, saying Huck's conscience is "immoral" might be true 
   in a way, but you only said "deformed conscience" before.  So you seem to have 
   upped the ante in a way.  The reason you are saying his conscience is immoral
   is not clear at this point.  That would be clearer, though, if you had put the 
   "A common misconception ... " section at the beginning of the first paragraph(!)
 
     On the second page, it would have been better to explain in more detail why you
   are saying the version of Christianity to which Huck was introduced was "misinformed"
   and "deformed."  Exactly which features of the religion he was taught are you 
   referring to?  (I'm not saying you are wrong, just that you haven't explained
   why you are saying that sufficiently.)
     
   Some smaller points: "the Widow Douglas" sounds better than just "Widow Douglas"
   to me.  On page 4, the paragraph starting "At the beginning of the book ... "
   has a good opening sentence, but then the next sentence is essentially just 
   a repetition of that.  Later, you use the word "prank" as a verb, which is
   pretty colloquial for this kind of writing.
