At what point in the story have you decided that it is all fair in war and love? you go on steal other's wives and then give all fair in love and war concept ..then it would not work..yes in this case things are not as black and white..Esp since Meera fell in to the trap..and you and I know that this is a trap..Desai might have come to love her over the time but his intentions were definitely not pure since the beginning. So why do you think it is morally correct just because they ended up loving each other..Does that mean the path to end is not taken into consideration as long as at the end it ends happily for Meera?
Also you one more way to look at this..look at Meera angle..She is definitely an accomplice in all of this with Krish..at least that's what every one thought until she played the guilt card in last episode..If you have faced guilt for getting fucked by Jai..then you should have committed suicide for things that your husband made you do in in 3 parts or what you willingly did yourself..but she didn't and this part she enjoyed with Jai and Ashish too so why should it end happily for her while Krish should suffer?

Which ever way you look at it..its not morally correct ending for anybody to have happy ending here..all of these three characters are messed up...All three should suffer for the choices they made in this story.

 1. You are making it sound like Desai has forced or blackmailed Meera into loving him which is not the case.

2. Of course Meera is also responsible for this. She likes to believe that she only sleeps with other men to fulfill her husband's fantasy, but in reality, she enjoys it for her own enjoyment/lust. She always needs validation of the fact that she is not an whore  and Desai said what she wants to hear. 

3. I think if the story ends right now and the last episode is just an epilogue, it would be a great end .The alternative ending where Krish suddenly becomes a  Grade A level detective and exposes Desai would be too filmy.  Krish would not suffer as I have mentioned before, he would be heartbroken for a few days/months but would get a more loyal and simple partner for himself, he is already proven that he can charm anyone of any age group (from Nidhi to Parvathi and all the ladies in the second part)
