What I felt in today's scene, when Karthik talks about the past incident, is that, Firstly, Manish took the wrong approach to start with. Instead of attending to Karthik's anger making the young child understand lovingly, he chose the option of raising his hand, that is not the way to behave with a child, especially in the circumstances which Karthik and Manish were. Maybe Manish did try to handel things calmly for a while but Karthik acted stubborn and Manish ended up getting angry, but still raising you hand on a child isn't an option. Manish might have thought Karthik was too young to understand the actual situation but he could have at least tried, if Karthik didn't understand he should have let him be try to make small advances in the mean time and when Karthik grew older probably try to explain him the situation once again, who knows he would have understood this time at least. Secondly he sent Karthik to boarding like seriously, when the boy should have been between his loved ones, you push him away to be alone and now you want him to come back to you all.
Karthik simply wants what every child wants, to be loved and cared for to feel protected. Somehow Manish failed to do that, you can't accept a child to feel protected by a person who raised his hand on him. Maybe Karthik was being difficult, but aren't most children. Then Karthik was sent to boarding, instead of attending to his hatred and misunderstandings, the sent him to boarding to be alone, can you expect him to feel love and cared for by such people. He didn't get what a child wants from his family and he became hostile especially towards Swarna and Manish.
