He is very right, however he also acts as if fans are the ones that chose this profession for him, and he is making sacrifices for us.
He is making sacrifices because he was the one who chose this career, he is making sacrifices because he wants to become a Top fighter, he makes sacrifices because he wants great amount of money, so him and his family live well.
That is why he makes sacrifices, I don't think during the training camp the trainers tell them "Dude, you are not bleeding profusely enough! You think that the fans will cheer for you? I want you to finish this session with a fucking broken nose, the fans are the most important thing in the world, and you have to give them what they want!!"
