Hilchot Teshuva 2:10-3:1 (Responsibility of the Wronged Party, Definitions of Righteous and Wicked)

While the sinner must ask the wronged party for forgiveness, what is the responsibility of that wronged party toward the sinner? What does this indicate about his geneology? What should the offender do if the wronged party died before he had the opportunity to ask for his forgiveness? And what is the definition of the terms, “righteous” and “wicked”?
