Hmm.. Aadhi is indeed aware of the genuine grouse that creates Badris. 'You seem to be a man driven by ideology' is something he acknowledges first up.
We can see why Aadhi is the interrogator and not Abbas. Abbas can't see the other side and sees only black or white 'what sh*t are you talking man, endha nErathilaiyum neeyO naanO andha mAdhiri seyvOmA'. He is not able to see the human other side, even when it happens to someone close to him (perhaps he was not as close to Srinivasan as Adhi was in the first place)
Aadhi knew this externally. But only when it hits closer to home does he begin to realize that his fundamental beliefs are plastic. And then it takes another shock for him to recover and he has to take what he started to its natural conclusion. Very aware that he has not solved the problem in its entirety.
Though he says 'mudiththu vaiyungaL' Aadhi does not have a solution. He realizes the hopelessness of the situation.
Anyway, the reason I wanted to invoke KP is very specific.
Though Aadhi prides himself on being a 'romba nErmaiyAna komban' - it is only we the audience who is privy to the fact that he condones the killing of innocents as long as the cause is his, while judging Badri for EXACTLY the same.
This keeps coming up in various places in the film. What gives Aadhi the conviction that he is right? Merely being part of the establishment. And to what extent does he represent it? By playing by its laws (உன் முட்டாள்தனமான சட்டம், நீ நினைக்கிற எதையுமே செய்ய விடாது), or by circumventing the laws to serve the 'larger interests of the establishment', but then does it fully align with his சமுதாயக் கோபம் - or does he believe it does?
You can see the plainclothes vs. uniform reversals in many places (thanks to equanimus for pointing it out once).
The last time I watched it I was impressed by the scene where Badri escapes. Prasad and Narasimman - both wearing the police uniforms - aid him.
But what a difference between the two pretenders wearing uniforms. The one who pretends and serves for ideology lives. The one who pretends and serves the cause for -assumedly- mercenary reasons is killed. In fact Prasad may even be remembered as a hero who died in the cause of the nation!!
