In Arabic the word insaan comes from the word Ins, that is the one who errs, the one who forgets meaning the deficiency lies in the name itself.
No one is fault-less. Everyone commits sins.
Now the problem lies in How these sins can be stopped from being committed in the first place.
=====
When one sin is commited so often and it becomes rampant then it becomes accepted. Today in the western world if one has pre-marital intimacy its normal. To live with boy friends for many years before actually tying the knot is normal. Its even considered healthy.
If a boy is not dating by 13 then he has some social issues and is suggested to go to a counselor in the schools here.
So ... since there were no strict steps taken about the pre-marital relationships this sin became so rampant that it got accepted.
And according to your statement ( I do not live in India- and certainly not the India I remember) Today its very common in India and they realize it after they commit the 'mistake' and are sorry.
So eventually this sorry will turn in to , hey its my life, and then into, I want to understand my partner before I get into commitment and then it will become a norm.
So ... what is the solution?
forgiving ? accepting ? or setting examples that such acts are not committed in the first place..
Does chastity have no weight any more?
Secondly,
About forgiving.. who are we to forgive or not forgive. The person who has committed such sin should seek forgiveness from GOD.
About accepting, I cannot accept. Because this chastity is something we hope and accept from both partners and if one were to be indulged in that act then, it would only be fair that the person is honest enough to admit it.
If lets say sakshi does turn a good leaf, and she is married will she tell Alekh she was involved in a pre-marital relationship? Will Vasu then thrillingly accept her?

Now .. again I go back to my original statement if sara were to return as sadhana look alike her character will not be introduced as that of an immoral woman cause it wont go with her rep.
