OUAT Season 2 Finale Interview- Lana Parrilla Will Regina Sacrifice Herself To Save Storybrooke? 

Regina didn't flip flop in Season 2. She tried to redeem herself on Henry's terms and failed, thanks to Cora's arrival in Storybrooke.

*Agreed.*

"F---- you all. I'm going to take what I want. It always seemed to work before. Why should I change for anyone? I try to be good and it backfires. When I was evil, it seemed to work out all right for me."

Nailed it.
