"Conor McGregor says it best, there is no anger or emotion or desire to hurt your opponent once in a fight.
The opponent is simply a blank faced moving target that you must put down."
Ooh, are you threatening me?
Im just saying that you would never speak to me that way in real life.
That other quote is evident in the way he fights. McGregor clearly carries 0 emotion with him into the octagon, that is clear for everyone to see.
