Things I don't understand with Mona being A

These are the things that I didn't understand after finding out that Mona was A. 


1.) Why did Mona want to get rid of the liars so badly. Mona has messed with Aria and Ezra, Hanna and Caleb, Emily and Maya, Emily and Samara and Spencer and Toby. Why?


2.) Why did she start sending them in the first place? She said that she started them because Aria, Spencer and Emily took Hanna away. But when they started they weren't friends and Mona and Hanna were the BFF's and POPULAR which is what she wanted in the first place isn't it?


3.) Ali was getting texts from -A to. Where they from Mona or from a different A, maybe the person controlling Mona? Or did Mona start the whole thing?


4.) Does Mona decide who is on the A team or does the person controlling Mona decide?


5.) What is the person controlling Mona's motive for doing this. 


For all that the A team has done to the girls, they better have a amazing mind blowing motive and a real reason otherwise whoever is on the A team is not getting any sympathy from me. 


Other Questions I have!


1.) Is the N.A.T club and A team related?


2.) Jenna and Garrett are always talking about "They are starting to suspect Ian didn't kill her", "There's nothing that can link us to that night". Does that mean that Jenna and Garrett killed her, or they know who killed her, or they were there and witnessed it?


3.) Byron and Ezra have both mentioned having brothers. Byron's was a drug addict and we don't know anything about Ezra's. Does this relate to anything?


4.) WHAT HAPPENED TO MAYA?!?!


5.) Are we ever going to find out who that blond girl was at the window?


6.) Will we find out who killed Ali, and why. I want to know exactly what happened on the night of her disappearance. 


7.) Why did Ali say "The four of you combined know more about that night than you think you do". Were they there when Ali went missing? Did they really fall asleep when Ali left the barn to go meet Ian. Sometimes you can block something out so much, you start to actually forget it. 


8.) Why was Maya talking to Jason and who was she talking to when she was at the bus station leaving to go to San Francisco. 


9.) Is the person controlling Mona (Let's call them Big A from now on) someone we know?


10.) Last question I promise! IS THERE GOING TO BE A PRETTY LITTLE LIARS MOVIE!?!
