My Irritation With Great Expectations Regarding Pip's Sister

There's a lot of background that isn't given to her character before Dickens decides to disable her.

If you read the first few chapters of "Great Expectations" by Charles Dickens, you would be introduced to Pip's sister.

Mrs. Joe is more than 20 years older than Pip, and she's married to Joe Gargery, a blacksmith who is the only one who cares for his wife's young brother. Immediately, she is portrayed as abusive, since Pip recalls her attempting to beat him since he was apparently home late from the graveyard in which he visited his parents' graves as well as the graves of his infant brothers when he is caught by an ex convict. Luckily, Joe protected him.

(This is basically the earliest version of a mean sister).

So, she's abusive. Why?

When Pip's sister invites some people to the Christmas dinner, she forbids Pip to talk and forbids her husband to object to anything rude she says, even if he disagrees.

So, she's controlling as well as abusive. Why?

Next, when Pip meets Miss Havisham and comes home again, his sister wants to know about what happened. When Pip doesn't give her a satisfactory answer (by her standards at least), she resolves to beat him!

Abusive, controlling, quick to be angered. Why?

And then, when she throws a tantrum because Orlick (a business man speaking with Joe and Pip), she is soon after disabled by someone hitting her with an extremely heavy object multiple times to the head and spine.

Mrs. Joe Gargery is disabled before we can have much background on her, which irritates me greatly.

This is my main irritation regarding Great Expectations, and I would like to show it by explaining my thoughts.
