Of all characters of Mahabharat, Draupadi’s character is probably the most complex and interesting, barring the Shri Krishna’s character. If I dare say, one can paint her as a positive character or a negative one, if one wants to. One can find enough of both, positive and negative indicators about her personality, such is her character.
She is said to be the prime reason for war of Mahabharat, by referring Duryodhana as a blind’s son. If possible, people will also attribute her beauty as a bad thing. What is important here to understand that Draupadi was not influencing Dhritrashtra or Duryodhana to become greedy and thus not allowing pandavas to have what was rightfully theirs, which is the main reason behind Mahabharat war in my opinion. Also, how one can explain the numerous wrongdoings, which duryodhana has inflicted on pandavas with the sole purpose of acquiring a kingdom, which was not theirs. Duryodhana has gone to the extent of killing pandavas, but strangely, somehow people choose to blame Draupadi and ignore these factors. Certainly, these things cannot be attributed to Draupadi and citing only one incident as the reason for Mahabharat war is probably going a bit too far.
On the other hand, lets examine the circumstances which Draupadi faced, and try to gauge reactions to these events. For example, how would a lady feel if she has to become a wife of five persons simultaneously, or how one would feel if someone is used as a material object and was lost to Duryodhana by her own husband, Yudhishthira. Being a queen, she was subjected to ultimate dishonour by Dushashana, that too before all the great people who were present there, like Bhishma, Drona, Vidura etc.
Draupadi vowed to not to tie her hair until they are dipped in Dushashana’s blood. I consider this fair, as she was subjected to lot more wrongdoings, and the pain of humiliation is much more to handle than anything else. And above all, I would have agreed this as a wrongful thing, if Dushashana would have been a nice human being, which I think is far fetched thing. Duryodhana even went further to suggest her as a fallen lady because she was a wife of five persons. What we forget that she was just obeying the wishes of her mother in law, Kunti. But history is full of such incidences, where a person is treated wrongfully even the person has acted fairly. Draupadi’s is one of these.
