Plot wise every character has his own reasons and intentions only for one reason to stretch the story as much as possible. I think that plot wise they're all in the hands of the writers. And we should blame writers then.
If he could help or just console Preeta as a friend it doesn't mean he would take advantage. It doesn't mean he should take some romantic steps. Of course, Rishabh is not that type of character who can ditch his own brother and take advantage of the situation. Rishabh is a good man.
I just think that he could help her out of friendship. He says it himself that he is always on the side of the truth. That time Arora family was on the side of truth. Unfortunately, they were all alone😒
yeah he should have consoled them right after karan left preeta on the road.
