Whether the entire good of human nature can be destroyed by sin?

❌ Objection 1 : It would seem that the entire good of human nature can be destroyed by sin. For the good of human nature is finite, since human nature itself is finite. Now any finite thing is entirely taken away, if the subtraction be continuous. Since therefore the good of nature can be continually diminished by sin, it seems that in the end it can be entirely taken away.

❌ Objection 2 : Further, in a thing of one nature, the whole and the parts are uniform, as is evidently the case with air, water, flesh and all bodies with similar parts. But the good of nature is wholly uniform. Since therefore a part thereof can be taken away by sin, it seems that the whole can also be taken away by sin.

❌ Objection 3 : Further, the good of nature, that is weakened by sin, is aptitude for virtue. Now this aptitude is destroyed entirely in some on account of sin: thus the lost cannot be restored to virtue any more than the blind can to sight. Therefore sin can take away the good of nature entirely.
