Rishab is right it was his parents mistake .
If you see from the starting they were always with Ritwik because Ritwik has gone through so much loss but they never given Rishab there first priority .
Mamta and vp should have understand that not only Ritwik but also Rishab lost his dad he was at loss too ,kids with broken families always go through with so much loss that could bring either a new positivity in them or a negative in them. Rishab was a child too and very new with what's going when his mother would take extra care and show to another child he might have felt bad and angry and Rishab always wanted VP to fill in his father's shoes for him but VP to have Ritwik his first priority .
But I cannot justify his actions at all I don't understand wheather he was insecure that he will not get a penny if Ritwik and Shivam are there because he is an outsider .
If Mamta and vp alongside Ritwik would have expressed Rishab how much they love him and how important is he for them he might not changed into a cunning man ,no one is born criminal, situations and bitter experience s make them One . If Mamta and vp could fill in the gaps there family would be happy and complete .
