well, let me get to the actual topic. i have seen members still speaking abt ruining raginis character and this was said by RS as well, tht spoiling sisters relationship did give him nothing!
but i have another POV to some extent. i think sisters relationship getting spoiled is a reality n this makes bidaai even more realistic. that was a phase that was "required" in bidaai. i agree that i did not give anything.... but what it gave later is what we must see. when ragini came to know abt the truth, she cudnt believe. now she will give n do everything for her sister, just like sadi did. its a fact n its an open truth that ragini never did what sadi did. ok i wont blame ragini, yeh she didnt get the opportunity, nothing came in front of her...atleast not sacrificing herself or her life like how sadi did but now she will find for one and give her life for her sister! now their relation will be even more bonded. now they will love each other even more unconditionally. such tiffs happen in relationships only to make them even more stronger.
therefore for me, ragini was a great sister n a person even before n is even now. i wont blame the directors/producers/cvs for ruining her character. for me it was wanted if not needed!
