The Witch of the East could have gone evil, too - she hasn't been mentioned, but the Wicked Witch of the East is the only known Witch of the East in the Oz books (as far as I'm aware). Perhaps that's why Zelena was only worried about getting rid of Glinda: she knew the others were just as unstable as she was and that once Glinda was gone, they would quickly side with her.
