Is the question who is a better life partner for Maya or Manvi? Then definitely I get this comparison of Love and Lust
Did Maya leave Vikram because he was lusting afterher? No. Her plan was using him to get a new identity, she didn't leave him because he touched her when they were practicing karate, she agreed to marry him when he asked her. Any "normal" person would never have agreed to marry a man who wasn't worthy of her, as you have stated, Maya betrayed him which ruined his life
Vikram was a good human who helped her, nursed her back to life, taught her so many things including self defense she used on him. He changed after Maya's betrayal
But this Maya, herself is result of MJ's betrayal, whatever she is doing now including killing people in "understood" because she wants revenge but change in Vikram is HIS fault, He is a lusty man
Now think about Manvi's life without MJ and Vikram's life without Maya
Why is it that everything Maya does is defended and her victims are blamed, she is applauded for torturing people?
