According to a Korean maxim,  If there are three persons, including me, the other two persons must be moral exemplars for me.  This maxim emphasizes that we learn from both a bad exemplar and a good exemplar. We learn from a good exemplar when a person gives us an opportunity to imitate his or her good behaviors. We also learn from a bad exemplar when a person gives us an opportunity to reflect on immoral behaviors
