Why Maya cries at the end :
As she stated before she was recruited directly from high School ,has no friends(except for the Lady that got killed during the bombing) , no loved one and spent the Major part of her life as an adult hunting for Bin laden....so catching bin laden was the only Goal she ever knew and after that was gone she did not know how to proceed her life....remember she starts softening right after the Pilot asks her where she wants to go....that Moment she realized that she does not really have another Goal in her life and does not even havce an answer to the question where she wants to go.....i always disliked the thought that she felt bad for being responsible of killing bin lkaden....so the reason she cries is that she just realized hopw empty her life is
Trolls dont have an opinion....just an urge to compensate their frustration about themselves!!!
