I know everyone things RK did good things as well like saving the family and everything, but she also had done a lot of good things, made him believe in bappa again, united him with his mother and saved his life, he also forgot all that when he left her, so I don't know why everyone is bashing madhu when they didn't bash RK at the time.
The past comes back to haunt you and that's exactly what is happening with RK and he needs a taste of his medicine. Everyone keeps saying he has changed, how has he changed, he still praises himself instead of madhu and everything is always about him, so i don't see anything changed in him. He is just obsessed with Madhu, but that's not love, the day he starts putting madhu ahead will be the day he is in love with her and that hasn't happened yet.
I do want them to be together at the end but only after RK longs for her and realizes that he loves her.
I support Madhu 100% with her plan.
