Fear

"When fighting a person of higher ranking, I can fight more relax. For one, i am not afraid of lose, for two, i know he will take good care of me."
"But when fighting with someone of a lower ranking, it can be very stressful. Losing is a bad choice, and on top of that, need to have full control of all the technique."

Who said that it is unfair for a higher ranking person to fight a lower ranking person?
Stepping into the arena, the two person starts off with a very different mentality. The ranking system nowadays doesn't really seperate people based on their ability. Even if it does so, the ability difference is not as vast as most people think.
And in Karate, although physical ability is important, the mind power is as important as well. With such worry and fear, one can hardly concentrate and bring out the best in his or herself.
