Because she truly loves Kanha as her own, because she doesn't differentiate between adopted and own (like any decent human being should). Is that wrong.
True she had no answer to umed's ques that what was the alternative ... but did maiyee have an answer to her question - would she risk veer/vansh to save the other ... How can you ask a mom to choose ?
Umed only in the end said that he trusted veer to bring both the kids back safely ... but his rest of the speech was utter nonsense ... he pretty much said - ya! we did kanha a massive favour by keeping him in the house but now we don't mind sacrificing him to save yuvraj ...
All of them are differntiating between adopted and own ... this is why adoption agencies are reluctant to give the kids to young couples ... as soon as they have their own, they start ill treating the other
even veer for all his faltu ki bravery risked kanha's life ... Would you use one of your own child as bait for a criminal ? Would you take one of your own child in a place of criminals where guns are routinely fired ? Kanha could have been killed at a dozen different points ... the only reason he was not was becuase avinash was too stupid a villain ...
And somebody should give a dressing down to dadaji and umed ... they call themselves thakurs ? ... True thakurs or true men would give their life to protect innocents ... they would not use an innocent child to get what they want ... they wouldn't decide on sending a child to his death.
I think i have opposed every single of ichcha's foolish decisions till now even the utterly stupid one of hiding all this from veer ... never thought i would side with her ... but today, seriously how do you ask a mom to choose ?
