First of all, by writing RK's past sarcastically, here in this post, you have utterly disrespected it. I wonder how would you have felt if Madhu's too might have had some dark past and it would have been insulted like this. (Ballu thingie was Padmini's past, Madhhu's life only was in danger but its Paddy and Trish who had faced everything, that is why I consider Ballu thingie to Paddy and Trish's past.).Secondly, after what RK has gone through in his childhood, it is very much expected that the attitude, anger and frustration that he got in his childhood became more deeper as he grew up and hence, he is always gonna be like what he is now.. The only difference in future that we expect is that every layer of his character will be seen by us in a positive light rather than in a black, evil or grey light..
Redemption would take time when it comes to RK because its RK who we want to do redemption !!
Ofcourse , if he has a dark past, then he can't be forgiven of what he has been doing to Madhu. That is totally not accepted but that doesn't give anyone the right to DISRESPECT his past !! And the same applies to you!
I had seen you saying that if RK really does something good so that he is forgiven by Madhu, and that means that you too are a RishBala fan.. Being a fan, you should respect both the chars and not just one to defend the other !! If people here are talking some insensible thing, then that does NOT in any way mean that you too would go on disrespecting a char or his past !!! And you call that being mature? Playing tit for tat?!?! Hats off !!
