In the end, when you come at your student with an attack, he will defend the way he has been trained. He won't run, even if that is clearly a better option. He won't pull a handgun he has hidden under his gi, even if it would be prudent and justified.
There are levels to this. Who decides what is right, what should be recognized as competence and rewarded?
In a self-defense class, the 'end user' is the student. The students are the ones who will or will not be kidnapped, raped or murdered as a consequence of what they learned. The people who decide what is 'right' and what should be rewarded (with rank or trophies or...) are the senior members of a system or the tournament judges- people well removed from the delicate place where rubber meets road.
It goes beyond martial arts, though and into every aspect of our society. In much of our lives doing a good job is not rewarded as well as giving the impression of a good job. I'm coming to understand (I'm a little slow, this may not be new to anyone else) that big bureaucracies and government run on paper, not on results. A spectacular success does not have as much impact as a spectacular report about nothing at all. Good organizers are not promoted as readily as poor organizers who document great organized systems. No one looks at the systems, they look at the documentation. In some areas (a job I held once comes to mind) even the audit system designed to check this has become a friendly game of "I'll show you my cherry-picked examples and you show me yours and we'll award each other certification."
The 'good' students are the ones who make sensei happy. The 'good employees' (and future upper-level management) are the ones who make the present upper-level management happy. It has taken me a long time (and it is quite disturbing to my INTJ nature) that dedication, insight, hard work and even brilliant success aren't the keys to being in a position to change things. Success is not what the people who make those decisions, the ones many steps removed from the line, value.
At street level it is important- dedication, insight, hard work, compassion- all lead to the occasional brilliant success of a life saved or turned around, bad stuff prevented, good people safe to walk the streets. But do it for yourself. Do it because it is the right thing to do. Do it for the people who live with you at that street level.
Just be aware that the smiling face of someone freed; the person who you got to in time and has a chance to live are all messy and meaningless to the people who decide what is right and wrong; what will be rewarded and punished. The clean sheet of paper (with no typos or misspellings) is more real to them than reality.
