Aman has not truly tried to understand Roshni. The one hardcore evidence he had was when they were in the dark forest; Roshni was willing to give up her life for Aman’s. Aman did not do any favor to Roshni when he jump in the deceit well to save her, because she went in to save Chotu. And the sole person responsible for all this mishap is none other then Aman himself because of his father’s deal.
With all of this said and done, I do not want Aman to bargain with Jinn for Roshni’s life. I want him to have to do some hardcore task in order to get her life back. Aman has to be redeemed.
