Pelagianism is a theological theory name after Pelagius (ca. 354 – ca. 420/440). It is the belief that original sin did not taint human nature (which God called very good), and that mortal will is still capable of choosing good or evil without Divine aid. Thus, Adam's sin was "to set a bad example" for his progeny, but his actions did not have the other consequences imputed to Original Sin. Pelagianism views the role of Jesus as "setting a good example" for the rest of humanity (thus counteracting Adam's bad example). In short, humanity has full control, and thus full responsibility, for its own salvation in addition to full responsibility for every sin (the latter insisted upon by both proponents and opponents of Pelagianism). According to Pelagian doctrine, because humanity does not require God's grace for salvation (beyond the creation of will), Jesus' execution is devoid of the redemptive quality ascribed to it by orthodox Christian theology.
