Whether fear excuses from sin?

Objections

Objection 1 : It seems that fear does not excuse from sin. For fear is a sin, as stated above (Article [1]). But sin does not excuse from sin, rather does it aggravate it. Therefore fear does not excuse from sin.
Objection 2 : Further, if any fear excuses from sin, most of all would this be true of the fear of death, to which, as the saying is, a courageous man is subject. Yet this fear, seemingly, is no excuse, because, since death comes, of necessity, to all, it does not seem to be an object of fear. Therefore fear does not excuse from sin.
Objection 3 : Further, all fear is of evil, either temporal or spiritual. Now fear of spiritual evil cannot excuse sin, because instead of inducing one to sin, it withdraws one from sin: and fear of temporal evil does not excuse from sin, because according to the Philosopher (Ethic. iii, 6), "one should not fear poverty, nor sickness, nor anything that is not a result of one's own wickedness." Therefore it seems that in no sense does fear excuse from sin.
