When we go out from our home to work, school, college etc. We may come across good or bad situation for which we will build frustration in our mind and heart and coming back home we throw this frustration on our love ones, friends or sometime even our hobby but that is when we have nobody around us. We remove frustration on our loved ones because we know they will still be us in whatever case. But what I saw RK, he only remove his frustration only on his pottery that is his hobby if everybody remember how he was making that pot thinking Madhubala in his mind. This frustration is in mind of Rishabh from childhood may be because of his family ignorance if remember he told in jail ke 'mera ghar ek makan hai and there is nobody to send me food' (something like this).
He just grown as ignorant child may be or something like that. He knows the word pain a lot if remember how he was sitting beside poolside with his drink in hand. When he was saying that word pain to Malik you can truly see pain in his words. But this pain is not of that char din ka jail but because of that frustration which he never get a chance to share, because of that loneliness which he feels whenever he goes back to his home.
If we see around Rishabh was disturbed child and may be stardom must have forced to him too or from childhood he must have been exposed to stardom and so he wants to force it on Madhubala. Rishabh also started finding comfort in false world and so started enjoying it and then this Rishabh turned to RK and when his frustration turned to ego himself he do not know and after so many years when some girl called him by his name Rishabh Kundra all of his pain came in front of him and now he wants to finish it by his stardom because he feels that this stardom had finished his frustration too but cannot realise that it has been grown by years. He also knows that his gfs do not love her but still he searches for comfort in their laps but cannot, he searches comfort in drink in all other thing but cannot. Even he married Madhubala in mere frustration and he needs someone badly.
As it is said by someone "A heartless person had cares ones a lot".
