Sure Karthik is longing for love from his mother, sure he feels that she negelcted him in favour of Angad, but does that mean that he has to go to such extremes to gain his mom's love??? Did he have to plot and scheme against Angad....Angad, who always respected him....Angad, who always looked at his brother fondly???
Did he have to rope Kripa's best friend into betraying her, did he have to be so snobbish as to think that Kripa was not worthy of Angad, did he have to kick her out of the house, did he have to kick Angad out of the house??
Did he have to rip Angad to shreds when he was in jail, telling him that she was a disgrace to the family, that their mom was ashamed, did he have to abandon and cast his brother away like a piece of dirt???
Not to mention that he is indirectly responsible for Kripa's miscarriage, as he was the mastemind behind Angad and Kripas misunderstandings, and turmoil, the first time round!!!
I'm sorry, but no remorse was shown by him at the time, so why should I feel sorry for him now. He could have easily spoken to Naina, approached her the way he did on Thursday...he could have spoken to Angad, as a brother. As it is, Angad didn't exactly get love from his mom, but he never stooped so low in an attempt to gain it.
