Why does the master always instruct the disciple on what to do.  Murder someone for example.  But if the master really wanted something done they should do it themselves rather than to use the situation as a test.  Your disciple is just there to learn your teachings.

Rather than lose a valuable disciple I would also raise or pass on my teachings to master disciples who then hand these teachings to master disciples and so on and so forth.
