Whether the will is a subject of sin?

Objections

Objection 1 : It would seem that the will cannot be a subject of sin. For Dionysius says (Div. Nom. iv) that "evil is outside the will and the intention." But sin has the character of evil. Therefore sin cannot be in the will.
Objection 2 : Further, the will is directed either to the good or to what seems good. Now from the fact that will wishes the good, it does not sin: and that it wishes what seems good but is not truly good, points to a defect in the apprehensive power rather than in the will. Therefore sin is nowise in the will.
Objection 3 : Further, the same thing cannot be both subject and efficient cause of sin: because "the efficient and the material cause do not coincide" (Phys. 2, text. 70). Now the will is the efficient cause of sin: because the first cause of sinning is the will, as Augustine states (De Duabus Anim. x, 10,11). Therefore it is not the subject of sin.
