I think Starlight Glimmer knew Twilight before she went to Ponyville. From the looks of the photos, she looks like a powerful Unicorn. Maybe her and Twilight were "Friends" in her mindset, but then she discovered Twilight's talent got her to be Celestia's apprentice, she feel un-special because her and Twilight were no longer equals.

This could be an act of revenge or trying change the world in what she thinks is for the better.
