Nothing
Everything happened as he had intended. The encounter between Arnab and Abhinav, his victimization, the transfer of the 10 lakhs to his account, and Arnab's complete financial loss. Yup
Everything happened just as Karma intended.
Even when he went to the government official to discuss his pension, it was Karma who paid the official and urged him to make Arnab use bribes.
And when Arnab had lost everything and had no other way out of his predicament.
It was finally time for Karma to see the man in person so he could shape him into the ideal pawn.
It was a dreary day, with the sun buried behind large clouds in the sky, and an elderly guy sitting alone on a park seat.
When Arnab felt his life was gone and he had no choice but to commit suicide, a chilling voice from behind him called his name.
[Karma: "Mr. Arnab?"]
When he turned around, Karma could tell by gazing into his eyes that the man was debating whether or not he should live.
