What is the difference between mockery and satire?

Mockery is a cowardly way to attack someone in hopes to degrade them. In the book Oliver Twist mockery is used quite a bit by the upper class. Those of high social status thought of those of lower status, as to be mediocrities and as just those who stole and had no way to make a living. In the same way Oliver Twist is mocked especially by Mr. Bumble. Oliver is thought to not be a gentleman, even though he truly was, but more precisely to be an individual who was just another underprivileged boy. However it is made a clear point by Charles Dickens that these accusations toward the lower class in the British Society, were nothing but a bunch of foolish and childish ways to look at the lower class. Charles Dickens analyzes the British society and exposes how corrupt it was by writing the book Oliver Twist. He writes the book in a very satire way, in hopes that people will fix what is wrong, and anticipates that these fixes will be for the better of society. Through his book Oliver Twist, Charles Dickens is able to make the British Society look really corrupt and show the reality of what was really taking place during the time period. Charles Dickens is very effective in accomplishing this goal, and it is very evident in his book. For example when Oliver tells the old gentleman that he’s staying with, that it would be in his best interest to deliver the package, he agrees and allows Oliver to deliver and hopes that he comes back. However Oliver happened to be kidnapped by some of his old acquaintances and doesn’t return. When the old gentleman realizes that Oliver has been gone way too long, he automatically thinks that Oliver took the money for the better of himself. And so this shows how the upper class made terrible pre judgments of the poor. And so by including that passage into his book, Charles Dickens is in one instance, able to show his readers how corrupt British society was, and he portrays it in a very satire way.
