Confusion regarding Savita Taai

We all know how muphat she is from the beginning. But now she has mended her ways right? Accepted Archana and living peacefully, but is she still a vamp? In the mahasangam episode why did she help to replace Indira with Zara? Earlier when Zee celebrated it's 20th Anniversary she helped Buaji from Puner Vivaah to get the cd against Aarti. Is she still negative?
