Heartless Samrat threw his pregnant sister out of the house with no one daring to oppose him simply out of fear. They didn't want to be thrown out because they love their cushy lives! Just like Urmi, Aditi is all alone & has to take care of the child in her womb. Although Urmi's mother, sister & brother have sympathised with her, they ultimately failed her for not rallying behind her, & for giving in to Daadi's crappy thoughts. So really, there isn't much of a difference between Aditi & Urmi.
Both women were also foolish...gave too many chances to men that were unworthy of their love. They made some wrong choices. But neither of them deserve the treatment that was given to them. No one does.
Aditi & Urmi both are victims of Samrat & his ego. He wanted to dictate both women in his life. And both women were failed by family. Tragic.
