Bhavi I too am baffled as how can a human being take so much. I even made a post on that.
9 years is very long time.
But at the same time I agree with Shweta. It sure depends on individual as well. I have said few times KC is very complicated character. He really does seem completely broke from inside. I sense dark emptiness inside him where he's not able to see anything at all.
Such people are rare to find. KC cares more about what his loved ones than anyone else. And his wife sure meant to him everything. If he can't save one person that matters most to him; what good is he as a person; that's what he feels.
I know an individual who intentionally failed 12th science exam and walked proudly to get mark-sheet of 0 in every subject. But inappropriate joke from his brother; guy was not able to eat or sleep properly for 2 weeks and remained in bad mood for months. Very rare but they are.
But I still want or hope for more answers from the story. Just 2 mirror scenes are not enough for me. Even if he is shattered; still can't spend 9 years playing PSP, cards and drinking. So I am still not able to understand what took place here.
Was it shown just for hack of it or there is a purpose?
