Sorry dear, not agreeing with your views.
For Kabir's past , Kabir himself is responsible. He is responsible for entering in a relation about which he was not fully convinced. He took a chance & believed Shreya which backfired. That night he could not control himself & entered in a loveless ONS . Which helped him come out of a abusive marriage but destroyed Tarini's life completely. He is responsible and he admitted it . Because Shreya abused him , he decided to go to the top using any damm route. He is responsible that he was still allowing Shreya (though hate) to still dictate his life. He was responsible for arousing some desire in Malvika's heart by flirting with her in starting days, which leads to such bitterness in Malvika and Ananya was at the recieving end of her plans & plotting.(I know nobody ever pointed out this , that actually Kabir himself gave some small reasons to Malvika to feel that she has a chance, as a egoistic spoiled rich girl she never accepted, Kabir can neglect her for Ananya ) Yes, he never ran away from accepting his mistake , that makes him a person to respect. So, he needed to make efforts to clarify himself to Ananya's close people.
Now, coming to Ananya, she is a pure girl and never commited any such mistake. She loves Kabir. Believed Kabir and for her Kabir is the only person whom he believed to be her anchor who will sail her to the truth of his father. She believed him before she actually meet him & believed him after meeting him, come what may. But, how she can be responsible for her father's deed? ( may be he was wrong or may be he was not) . Her father & she both are completely different entity, two adults & it is not her mistake or decision to be SK's daughter. It is another hypocrisy of our society is that if any family member does some mistake all the family beomes guilty. "Log kya sochenge" is the word we grow up with. Here, Ananya has nothing to prove to Kabir's family as its SK not her who was accused then.This is the reason Kabir's Bhabi was not bitter towards Ananya & she behaved with her sweetly ( not fake sweetness) So,no way, Kabir & Anaya is standing in the same platform.
