Principle: One should criticize the works or actions of another person only if the criticism will not seriously harm the person criticized and one does so in the hope or expectation of benefiting someone other than oneself
Application: Jarrett should not have criticized Ostertag' s essay in front of the class, since the defects in it were so obvious that pointing them out benefited no one
Jarrett hoped to gain prestige by criticizing Ostertag.
