otherwise it would not help to justify the sinner in the sacrament of Penance. [1] We can easily see how this is possible with regard to sin. For other actions done through fear have some evil or loss annexed to them, on which account they are involuntary under some respect; while aversion from sin is wholly good and reasonable, and so there is no reason why repentance for sin from fear of hell should not be simply voluntary and in no respect involuntary. [2]
[3]. Inasmuch as bad actions done through fear are simply voluntary, it would follow that they are imputable to the agent, so that fear does not excuse him from sin. And this is true of such actions as are intrinsically bad and against the natural law. The Church has always considered those to be apostates who through fear of death or persecution deny their faith, though less culpable than those who renounce it without excuse (Can. 2205).
However, with regard to positive precepts, grave fear ordinarily excuses transgressors of them from sin. The reason is, -because the legislator is not presumed to desire that his laws should bind when their observance would entail such grave consequences to his subjects. Divines, relying on what we read in Holy Scripture, teach this doctrine concerning the positive law of God, and it will be all the more true of positive human legislation. 3 But if non-observance of a law or a command of a superior would cause great damage to the common good, then the law or command must be obeyed, even with loss of life; for private advantage must yield to the requirements of the common weal. And so a soldier must stick to his post in war, even at the risk of life.
SECTION IV
On Violence
i. Violence or coercion is the using of greater force than can be resisted to compel another to perform some action against his will. In certain connections the person who suffers violence is said in English law to be under duress.
It follows from the definition that violence is from something external to the agent; no one can offer violence to himself; and that the subject resists to the utmost of his power.
