He holds his hands and fingers in his opponents face on purpose, in order to measure distance and keep them at bay.
But it is a choice that he is conciously making, well knowing that endangers his opponents eyesight, and in a lot of his fights actually lead to eye pokes, in some cases multiple per fight.
He could choose to not hold his fingers in his opponents face, for example at neck height, again, he chooses not to do this. He could also choose not to employ the outstretched arm technique at all, he chooses not to, disreguarding the penalties and more importantly the dangers that it brings.
He is a selfish character with 0 honor and respect for anyone other than himself.
