What I think this book has with being a leader?

In the book When she was good the main character is talked into running away from home by her sister who I think is a bad leader. It was her idea to run away from home and she still does not help her sister with work or anything they need to survive. I mean leaders they do not always do everything but they are supposed to be the ones who support the most. Also I find that leaders have to either have the best ideas or be strong because they can not have themselves messed up and let other people get to them. That is why i would say that both the main character and her sister are very bad leaders.
