i think they intend on showing that suraj has changed...and now he respects women...so i think what he did was right...when a woman is abused, it is not right for a man to just keep standing still...and suraj didn't do anything when vivaan abused imli the 1st time..i think it was only when he involved his name that he finally lost patience...during bandua track, when vivaan uttered chakor's name and taunted him,suraj was burning with anger and warned him never to utter her name again so had he mentioned chakor's name in this situation suraj wud have killed him...
