Who are you fighting for, Katniss?

In the book, "Mockingjay", by Suzanne Collins, it seems as though Katniss is able to cooperate with the rebels (Who she was taken 'capture' of not to long ago) rather than being able to cooperate with the capital (Who had more experience with her). I believe that is because she was born to be a rebel from the beginning, not follow the rules. It comes natural to Katniss, especially when innocent people are brought into 'her' mess. Katniss, the natural born rebel, will try her best at succeeding the position of the rebels mockingjay. Not for only for her friends, not only for her family, but the innocent people dragged into this nonsense as well. Its her duty to protect those who are not guilty. She is the mockingjay, it is her.

I believe Suzanne Collins wants me to understand that Katniss isn't becoming the mockingjay because she is forced to anymore, no. Katniss must become the mockinjay because it is her own will to save all the people she might put an end to. She wants me to realize that she can't back down now, not when she has added fuel to the fire. It was as if she was chosen to fight against the rebels all along. Suzanne Collins wants me to know that now its Katniss's choice to make her own decisions, whether they are for a good cause, or bad.

I think this whole time she was on the rebels side. Almost every move she made proved my theory correct. All this time, she wanted all the people of all districts to stop their hunger and put an end to the capital, which also caused it. She couldn't stand by and watch her people suffer, she had to stand up and fight. Katniss did not fight for her own district, family or friends, but all the innocent people that suffered as a whole by the capital.
