Arnav cheating is not mistake it's crime and Sin.So blaming destiny for Sins you commit is not understandable for me.It is not a mishappening or accident which u can call that it happened because of destiny.Going by this any defaulter or criminal will blame destiny for his crimes and sins he or she will commit.So for me blaming god or destiny for wrong doings is unexplainable.
The God angle was shown from Nandini's perspective, It was shown in way for girl who was getting abused met someone very caring an ideal kind of a person, It was not shown from Kunal's perspective...EMA is wrong i agree but how can u say those person who are committing this cannot be good, They are cheating with there partner its definitely there mistake but that doesn't mean they dont have any moral values left regarding other ppl related to them, They don't any humanity left..What is destiny as per you, Anything that happens unexpectedly in our life which we didn't knew will happen we name it as Kismat destiny weather its good or bad, Didn't ppl say shayad bhagwan ki yahi marzi thee when they dont understand things, It makes them feel better...Regarding Jajbaat thing what is jajbaat it simply means feelings which include everything love lust attraction etc so what is wrong in saying it as jajbaat
