I dont see anything to compare between them. Their motives spoke what thay had in mind. And they both came with good homework.
Deepali was only doing the damage control what little she could. She knows and so do we what popularity Puneet has outside when compared to Gautam. Puneets violence, his bitching, and his ever flipping mentality, daughters tweet has only added to his negative image outside, he doesnt have fans like Gautam. Deepali knows this, she is an aged, experienced woman and hence she played her cards wisely.
Mohit was a typical brother, but so was Bakhtiyar, the difference is Bakhtiyar crossed the line with statements like "moti to tum bhi ho", "tumhare bachche tumhe dekh rahe hain", and all his comments came across as trivial and personal that were uncalled for. Mohit picked the most controversial things ever said about Gautam, like funeral, death threat, things no brother or family could overlook. And no game justifies one having death wish upon the other player, or planning their funeral.
Neither Deepalis oh-so-kind-and-humble appearence is gonna change Puneets image, too late, nor will Mohits attitude affect Gautams fan following, he is too popular for thatπ
