Damn, that's brutal.  Sorry about your friend.  Did he quit after that or does he still practice?  I do goju-ryu and yea, the big focus is on control and it's why beginners are the most dangerous because they lack control.  I'm only a kyu belt so I never really get to train with those that have control unless it's the sensei's or some of the black belt senpai's.  Even then I get nervous because it's my own lack of control that generally causes me injury :P  They haven't done free sparring recently and with my injuries it's been a long time since I've really participated and so I'm nervous about it.  I'd be happy just doing katas and bunkai all the time :P
