I think so. Like some of the other posts said, it depends on the teacher and the individual.
The ONLY true test of a fighter is what he or she can do and no more. Form practice, sparring, self-defence practice and brick breaking are meaningless if the individual cannot withstand the burden of the REAL THING.
In a fight it is not just about dishing it out you have to able to withstand a blow too. On the street there ars no rules. An individual must be taught courage, fearlessness, and tenacity because on the street there are no second chances. It's either you or him. You must be ready mentally and phisically for any situation. That being said.
THE END JUSTIFIES THE MEANS !
