What are some difficulties oliver encountared and what did he learn from it?

Oliver had no upbringing or positive guidance. Oliver had to navigate through a childhood fraught with danger. Oliver manages to rise above his upbringing. Surrounded by selfish, ignorant and cruel people for most of his childhood, given no love, care, or tenderness, he still manages to maintain his kind disposition, and never gives into the low morals of those around him. He is, however, meant to be the exception that proves the rule. The fact that his happy ending is so very miraculous proves how important it is to be loved and cared for in childhood.
