Kareena Kapoor proved herself as a bitch in Tashan.

One of the reasons why Tashan is a flop is because of her action stunts  at the end of movie to kill Bhaiyaaji

If she really wanted revenge on Bhaiyaaji why did she dump Jimmy. This is really nice to have affair with a person, then cheat him and suddenly remember past and the person who was her real love when he comes across her and fall in "real" type of love with him, marry him and have a happy life. This is something really good to degrade our Indian culture and Kareena Kapoor has not only performed it in Tashan but in her real life too.
