Is Mia bad enough to be the new Sami?

Sami is now the mother figure on Days. Mrs. Horton is gone and Marlena(who I thought might replace Alice Horton) is in Europe, probably for good; so Sami needs a replacement for role of really bad girl. It looks like Mia has gone to the dark side from the shock of losing her baby daughter. Stephanie is also losing her moral center since boyfriends are falling away from her. Now Nicole is returning from prison and she has learned some prison tricks, I'm sure. Who will be the bad one now? My money is on Mia.
