He only wants to be part of the majority and he gangs up on the minority. His facial expressions are also very evil these days and he is not the same person he used to be.
Playing a game is different, but telling Rohit to cheat his own team is unethical and wasn't this against Karanvir's SO CALLED ETHICS he made.
If he wanted to play, he could have done it fairly as he could have brought majority from the blue team and played with his original team, this is deceiving his friend Dipiak too as he claims to be her friend, but he is backbiting about her whereas Dipika has never complained about Karanvir to Sreesanth.,
She has always defended Karanvir against Sreesnath and she has looked bad because of him in the captaincy task, but Karanvir is plotting against her and trying to manipulate Rohit though Rohit is no saint himself.
Eithe rplay it like Roil who accepts that, he is here to play a game because that is being yourself, not like Karanvir who wants to cheat on other people to go ahead in the game.
