You post is bang on!
It's what i said a couple weeks back that a person who forgives is a lot more bigger than someone who doesn't
And RK is asking for that one more chance and Madhu should give it to him considering she forgives everyone else.
And i also think that Madhu should take revenge, as i believe that she has the same dark capability as RK, we saw glimpses of it during the blackmail photo track, and have seen it since then as well.
Both RK and Madhu are similar, they love each other and have a humane side but they also can hate each other with the same passion and cause pain and hurt, ultimately they are the ones who can truly hurt each other no one else.
I feel sorry for you though, it's not nice for people to inbox you personally just because you like a character/actor. It's a tv show, you're young and you're allowed to like your own choice of actors and characters.
The Sultan fans like him exactly for the same reason, he' good looking so it makes it easier for them to like him despite him also having grey shades, being a gangster who either bribes people or pulls out his gun. He pretty much forced Madhu to go with him for Aryan's sake as well but they don't see it that way.
I think everyone is entitled to have their favourites, but they must also remember that this is a fiction show, it's not about a social message or an Aamir Khan thought provoking reality show.
It's fiction, it's filmy and it's a daily soap which means everyone should take it with a pinch of salt and enjoy it for what it is.
