I really liked Khali's calm behavior in response to that video and Sameer's remarks.. but I'm not sure about his thought behind this.. as he was talking to Dolly that "I have observed that only nice people reach the finals" so most probably he is controlling his anger just to be nice in eyes of people so that he could reach final.. so he is right but maybe unreal.. anyhow I still admire it..
On the other hand SAM was saying to Shweta that "What worst can happen than people will start disliking him and evict from the house" so now its beyond his control.. and he is being himself by not controlling anger anymore.. so he is wrong but real..
