Quite an interesting poll. I've voted for all.
IMO, the whole bunch of Bhanshalis top the list with Indu without any doubt being the worst of them all. The way Indu pressurized Shorvori for having the baby was the worst treatment any woman can get from her mother in law 🤢 All the Bhanushali family members always pressured PaRi for one or the other reason and I never had any doubt that one fine day they will abandon Teni too. It was because of their pressure that PaRi had to opt for surrogacy and in their hurry to forget Shorvori and replace her with Teni, somewhere led to Parth marrying Teni and everyone getting into this mess.
Next comes Parh, who is being the biggest jerk currently. I am not sure how true his love was for Teni because I haven't seen those episodes where he proposed her, confessed love to her or made out with her, but when he was sure that he will never forget Shorvori he shouldn't have married Teni. He committed to Teni without giving any thought to his or their future, and now that Shorvori is back, he isn't having any second though in believing that Teni is being selfish. It is yet to be seen how he treats Teni before she puts her demands forward, but I have no expectations from him given that he is a confused character.
Next comes Teni. She very well knew that Parth can never give Shorvori's place in his life to anyone else, still she agreed to Shorvori's stupidity. How could she believe that when Shorvori won't remain in the picture anymore, she will be get into Shorvori's place so easily?? It was a grievous mistake on her part that she hid Shorvori's illness from Parth, when she considered herself as his best friend. Teni has equal share of mistakes too that she has landed herself in this situation.
I am putting Shorvori last in the list because, though she did a huge mistake, she never had any vested interest in any of her actions. She took Parth's feelings for granted by hiding about her tumour and her accident from him, but it wasn't her who was directly going to benefit from those actions. Even now, she wanted to run away from them so that Parth Teni and family don't suffer after knowing that she is alive.
Coming to character butchering, Parth is hands down the most butchered character currently!!
