If I think about DD, I realize that she is not that bad... I agree that she did play a disgusting game but when I think about today's episode, I realize that she is not that bad at all..
Think... DD was a woman that had faced a lot in life.. Her hatred for middle class people is on one side... But we have to take it into our mind that she has struggled loads to be the lady she is now.. A strong businesswoman.. And that too without any male support..
And secondly, DD has become a hard-hearted lady due to facing a lot of hardships in her life.. Hardships that we may think only in our dreams.. But DD has experienced them and had lived through them..
And about faking her heart-attack.. Well.. Tht was definitely wrong indeed and I wnt support her for that... But in her mind, she has always had a dislike for middle-class people probably herself lived as a middle-class lady before getting into a successful business.. And her dislike for middle-class people might have also come due to her husband.. She was talking to a photo in today's episode.. Maybe she might hav developed her dislike for middle-class people due to her husband..
She doesen't want Roshni to suffer any kind of discomfort and so she played the game.. But what the lady doesen;t understand is that NOT ALL ARE PEOPLE IN THE WORLD ARE BAD...
And so we can deem DD neither as a POSITIVE nor a NEGATIVE character.. She is just grey...
