Ishaana that way is a more realistic character
Everyone has their own way of dealing with problems.Personally i would do anything to protect my family even if its wrong.So i understand Ishaana.
Also its not like we are seeing a con character for the first time.Let me ask you did you like ocean's eleven or dhoom or any other such movie?
If yes then if we can accept male character's as con artist then why not female?
