Rohan killed Amit and Zafar, who actually raped his wife, yeah... It was straight forward.
Now, Amit's brother (Corporator Shelar). He was not only Supporting his younger sibling's Crime but also after Supriya's death, Shelar visited Rohan's house and told, what his brother did was just right and did this Crime only on the basis of his Power.
And importantly, he was going to kill Rohan after Amit's Murder (or let say, planned suicide ;) So anyhow, Rohan had to kill Corporator Shelar, the bodyguard died accidently.
Now, character Nalawade is an arrogant inspector, such can be seen in almost every custody in India. Nalawade and his senior Inspector is the witness to today's Law and Order in India, who work for Bad people helplessly, just because of fear or desire for better life. In short, his act of releasing Rapists was actually on behalf of Corporator Shelar only!
In short, Society involves:
- Rohan & Supriya: True & Loyal people
- Amit & Shelar: Wealthy Bastards
- Nalawade & Senior Inspector: Today's Law and Order
