Although I agree with some of the stuff written about Laksmi in various posts, I think we all have forgotten the way Karan treated Lakshmi in the past. Her so called arrogance is what saved her from crumbling under all the sadistic pressure he imposed upon her. Physical marks fade, but ones inflicted on the mind don't! Has everyone forgotten the day when he left Laksmi alone in some place on their supposed honeymoon, basically disappeared while she ran around crying for help or when he locked her up in a room like an animal and left to destroy her family…all that is forgivable?
After Yuvraj's betrayal, the family was already in a vulnerable and weak condition. So when Karan did all this, he was aware of Laksmi's family's bad state... still he refused to back down, refused to even question Suryakant before making all his colorful plans. Is destroying someone, an entire family at that, a game that you don't even think about the consequences or gather sufficient proof before going about doing it?
Had it been someone else who had done all this, they could have been forgiven, but this is her husband we are talking about. Someone in whom she placed blind trust and respect and love and what not, only to find that that person never loved you, and married you only to destroy your family and then finally became an indirect cause of your father's comatose state.
Marriage is a very delicate relationship, built on mutual trust and respect. But once that trust is lost, the relationship is destroyed and it is not easy to mend it (not the same as family…. One always forgives parents and siblings no matter what…That's the way it is and will always be). In this case, Laksmi's trust in Karan has broken. At the present, Karan's face is a constant reminder for Laksmi of her father's condition. Maybe once Suryakant is well we can expect Laksmi to forgive Karan.
About saving her from getting raped, that was his duty as a human being. I think it is very sad that we are considering it to be a favor in return of which we expect Laksmi to forgive and forget. I don't think Laksmi needs to feel like she is indebted to him.
And finally, her family cannot convince her to forgive Karan coz they did not go through what Lakshmi did. It would be very insensitive on their part to say that woh tumhara pati hai, use maaf kardo. This has to be Laksmi choice which she will make in her own time. What Laksmi went though during her marriage to Karan is any woman's worst nightmare, so I say we cut her some slack [just my opinion of course :)]
so none of this was meant to offend anyone .. sorry if it did :)
