Cause this movie literally glorifies crime and crime lords, movie is basically made to show this woman was lured, persuaded or let say had no choice but join the crime world and run a brothel. Being a woman, it's shameful to praise such character for me.
If there's no choice in life doesn't mean you will become one of them, fighting takes guts which the real Gangubai lacked. But in this movie it's shown as a strong woman persona.
This movie was sister of Haseena Parker.
