For me, Khalil was with initially a negative character, because to entrust to get "by any means" lawful Farman,, it is possible only be absolutely immoral person, ready to commit any crime. And Shachzade also, for me, has never been a positive character. He is intricate, but not originally a noble, just sometimes acting under rules of etiquette or religion. But for me Shachzade is always the person who will "cross" through any other person, if he will be know that he will be go unpunished. That is: what mister - such and servant.
After reading that Durga gave false Farman, I think that the question of "why she had not killed herself?" should be clear. She deliberately sacrificed himself to save his sister, give her time to win. It's like in the Great Patriotic War, our soldiers rushed breast on German embrasures and machine-guns to save others.
