Punishment as a teaching tool
Punishment has a very high risk of destroying not only the desire, but also the ability to learn.
When one is the victim of a great injustice, there is a tremendous temptation to define oneself, and one’s life, at least partly in terms of this injustice. The victim mentality is a terrible mistake because it sabotages the vital process of learning how to have a happy life, solving problems as you go along.
