Both have their own reasons for doing what they did.
Both see the other as wrong. RK his shady we don't defend his actions but if U look at his from his point of view he has a silver spoon in his mouth and nobody there to scold him. We all need people to show us the right path and the moral of the story is being shown in the show. Yes he is taking revenge from Madhu but to him he feels she has wronged him by interferring and by placing him in jail. We all sow what we reap anyway. RK is paying and we have yet to see what sort of person he is.
Mukku is a guy with no backbone so the only reason he did what he did was because Madhu was there to influence him otherwise he'd have taken the money from his Mothers insistance. After all he seems like a follower than a leader.
Madhu took this as a cause to do right but she made it personal in due time. In her place she was helping a guy unable to fight his battles but to RK this would be cast as a busy body because at the time she had nothing to do with the guy.
Besides RK is what makes this show good nowadys otherwise its bland and full of floods and most of it is by Madhu and her sister. Its depressing.
