Have you seen the way Virat Kohli is..SID is quite similar to him in many ways.Thats his age. When he gets older he will become softer or will think before he talk and all the stuffs thats good about the other contestants.
I am not trying to defend him but thats the way he is because of his age. I can relate to him in a lot of way that myself and lot of ppl in his age would do.
BIgg boss would serve as a turning point for him.Once he comes out and sees the way he has shouted and vented his anger,it would surely change him big time.
So stop comparing his behavior to those ppl who are much much older than him in age and experience.
