Children are our future, right? Well, someone needs to tell the adults of Great Expectations, because, for the most part, they seem to see children as little savages who need to be beaten, abused, and maltreated into submission. From Mrs. Joe's Tickler to the casual cruelty of Mr. Pumblechook and his multiplication tables to the outright emotional abuse of Miss Havisham, innocence doesn't stand a chance. Or does it? Does Pip manage to stay innocent and pure in spite of his childhood?
Neither Pip nor Estella is ever innocent, because their childhoods are abusive in different ways.
When Pip is introduced to "society" as defined by Miss Havisham, his innocence is lost.
