LOL tbh, I actually don't think Sesha is the actual villain in this story? I think she was a former victim just trying to gain vengeance? So it's not wrong to root for her?
I actually think the main villain is Ankush? He killed Sesha's husband as shown in the promo apparently. And he mentioned to Hritik how he lost his respect and idenityt to get to his current position - I don't think he was joking like he said he was.
Actually in general, I'm actually hopeful that this show is going towards having more greyer characters than all-out evil villains!
