Whether a man is bound to accuse?

Objections

Objection 1 : It would seem that a man is not bound to accuse. For no man is excused on account of sin from fulfilling a Divine precept, since he would thus profit by his sin. Yet on account of sin some are disqualified from accusing, such as those who are excommunicate or of evil fame, or who are accused of grievous crimes and are not yet proved to be innocent [*1 Tim. 1:5]. Therefore a man is not bound by a Divine precept to accuse.
Objection 2 : Further, every duty depends on charity which is "the end of the precept" [*Can. Definimus, caus. iv, qu. 1; caus. vi, qu. 1]: wherefore it is written (Rm. 13:8): "Owe no man anything, but to love one another." Now that which belongs to charity is a duty that man owes to all both of high and of low degree, both superiors and inferiors. Since therefore subjects should not accuse their superiors, nor persons of lower degree, those of a higher degree, as shown in several chapters (Decret. II, qu. vii), it seems that it is no man's duty to accuse.
Objection 3 : Further, no man is bound to act against the fidelity which he owes his friend; because he ought not to do to another what he would not have others do to him. Now to accuse anyone is sometimes contrary to the fidelity that one owes a friend; for it is written (Prov. 11:13): "He that walketh deceitfully, revealeth secrets; but he that is faithful, concealeth the thing committed to him by his friend." Therefore a man is not bound to accuse.
