I think that Big A (real Alison) wants to get revenge from her twin sister Courtney (Red Coat) because she somehow betrayed her.

The switching identities thing was something they both did, but one of them pushed it too far (maybe Courtney).She tried to steal Alisons real life and succeeded.

Thats why Big A tortured and haynted "Alison" as well as the Liars.

I remember both the series song and "Alison" saying that: two can keep a secret if one of them is dead.

That explains Courtneys ctions against her twin sister.
