The good man is the teacher of the bad, and the bad is the material from which the good may learn.  Traditional Martial Arts teaches by continually testing its participants with progressively tougher challenges.  A beginning Martial Arts class may find themselves repeatedly punching targets.  But they will eventually learn how to control their bodies to best deliver a punch to this stationary target.

As the student learns, the lesson evolves.  The target may move, or change striking distance.  Lesson is built upon lesson in a limitless sequence.  This is why Martial Arts is more than just training or learning.  It is a way of life that, once learned, cannot be unlearned.
