Was Kumar planning on marrying Vedika to Ram and making him his successor? He's more competent than Shashi, business wise.
So Sahil Babbar felt threatened. He wanted Shashi and Vedika to marry so that their business stays within the family with no 3rd party involvement.
Kill Ram, eliminate potential threat to business?

That's why I am saying 'Land' is NOT the target. Hence, Nandini is washing off her hands. It's the FOREST we are looking at. If that is the case, then we the 'Nectar.'
