being spoiled and childish led to murder

[snokkums]

I was reading another post and I got to thinking. I think that Lizzie was a bit spoiled and childish. And when a spoiled childish child, or adult, doesn't get what they want, they have tendancy to throw temper tantrums. I am just thinking that maybe, just maybe, that Lizzie wasn't living the way she wanted (up on the hill) that maybe she threw a fit. It just happened that she killed the parents, and blaming Abby the most for not living up to standards. And getting mad at daddy Andy for choosing Abbys way over the daughters. Abby wasn't a relation, Lizzie and Emma were.
I'm just thinking Lizzie was flipping out and couldn't take it any more., I'm probably just letting my imagination run away with me!
