I don't think I completely agree on this.
Yes, I do agree that Swara wanted all MM members to forgive Ragini and give her another chance and always forced Laksh to accept Ragini. And she is wrong here. 100%. If she doesn't want to be forced in a relation, she should do the same as well.
But taking Ragini back to MM wasnt Swara's decision at all. Or it wasnt that she forced MM people to take Ragini. Everyone believed that Ragini had a memory loss and just for her health condition when Shekhar REQUESTED, Durga Prasad himself volunteered and said Yes. He said that Ragini would stay home until she recovers. And Swara went back only for her.
The only fault of Swara here is that she blindly trusted Ragini. But so did others (except of Laksh and Sanskaar). Everyone else believed that she has indeed lost her memory.
If Laksh was so sure that Ragini is pretending a memory loss, why did he let her manipulate him? When you don't trust someone, you don't listen to them AT ALL. But ironically, even after not trusting Ragini a bit, he kept doing everything that Ragini asked/wanted him to do.
For the current mess, I don't think Swara can be or should be blamed. The moment she realized what type of game her sister was playing with her, she slapped her and threw her out of the house. It was all Laksh's game plan to throw Ragini away from his life and to break SwaSan. This all mess is created by Laksh. Only.
Whatever mess that Swara created, is in her personal life. Between her and Sanskaar. She is responsible for that. But she is 100% not responsible for what is happening with MM members. Its is Laksh and Ragini.
