I that Mary was furced to become evil or is acting like she is evil.

It's complicated, but I think she is like, evil with good intentions, but good at heart, if that makes any sense... Like, she loves her family and wants the best for them and wishes that she never left them and wishes that she was a better mother, but she somehow for some reason had to leave, maybe for the same reason as their father, to protect them.
I just can't wait until Monday's episode so that will hopefully shed some light onto Mama B and her history. :)

its kinda difficult so im not rly sure

because of who she works with, but she does still have the mother in her, the fact that she gave sarah and chuck an escape route

After episode 7 I would say evil, but maybe Chuck can change her

I admit I haven't always believed in the good in her, but she has come to be a pretty sweet and caring mother :)
