The theological study of sin, error, and human wrongdoing; the branch of theology concerned with understanding the nature and consequences of human sin.
From Greek hamartia ('sin' or 'error') combined with -logy ('study of'), forming a theological term coined to systematically examine humanity's capacity for wrongdoing.
Theologians created hamartiology to answer a profound question: if humans are created in God's image, why do we sin?—the debate over this led to completely different religious traditions and philosophies!
