A bit extreme, but I get the general point and agree wholeheartedly. While on one hand she appears "noble" by sacrificing she has no qualms flouting basic ethics and human decency - being party to an immoral attempt to defraud another family, hiding major things from her family members and BF, insulting some people to please others, disregarding wows made in a temple, going back on her word, the list is endless.
Such people who would readily ditch ethics for expediency are actually quite ruthless and should be feared.
Everyone harps about family honour, what about personal honour? How can an honourable person go back on her word or allow herself to be party to deceit? What good is family honour when the individual members behave dishonourably - sooner or later society will see thru this.
In fact even keeping silent when you see something immoral going on is a dishonourable way to behave and RS is guilty of it (he should have spoken up against, not merely disagreed with, Manju's plan to foist an errant pregnant Neetu on unsuspecting Omi).
