Dont ever get confused by the bad guy
with all the focus on how to beat the bad guy.....
karate to me will always be about the confrontation of the self , You will learn , accept and grow if it's honest .
and knowing yourself and growing into yourself will be far more valuable and save you far more times than any technique of doom.
Know yourself , know your enemy and in 100 battles never be defeated .....
despite all the obvious benifits
, I think a real benefit is it seldom directly practical ...... something intrinsically yours that cannot be taken by anyone (even the high mucky mucks)
confrontation of self , a bucket of cold water to the ego , an eternal challenge , and a selfless and selfish pursuit to pay attention and do/be better.
Violence is a place were no one can hide , even from themselves.
But heck , you can probably find introspection in tennis too
