Name a crime and it's probably found somewhere in Moll Flanders' 400 or so pages. Adultery, bigamy, prostitution, gambling, thievery, murder, lying, and, oh yes, incest are all committed. Whether the characters get caught or not, nearly all of them have engaged in some kind of criminal activity or deceit. Some of the very worst kinds of crimes actually go unpunished, while some of the most inoffensive ones reap terrible consequences. So why all this bad behavior? Well some characters are just bad seeds, but others are trapped in awful circumstances and feel they just don't have a choice. Figuring out how justified or unavoidable each of these crimes are (if they are at all) is one of the great challenges and joys of tackling Moll Flanders. Prepare yourselves, Shmoopers. Your moral compasses will be tested.
Of all the crimes Moll commits, it's her casual attitude about the sad fates of other criminals that reveals exactly how corrupt she becomes by the end of the book.
Moll's claim of repentance falls flat at the end of the book, because once she is back in England, she enjoys her great fortune without making any effort to help out the people she has harmed along the way.
