Whether the sin is aggravated by the fact that the aforesaid injuries are perpetrated on those who are connected with others?

Objections

Objection 1 : It would seem that the sin is not aggravated by the fact that the aforesaid injuries are perpetrated on those who are connected with others. Such like injuries take their sinful character from inflicting an injury on another against his will. Now the evil inflicted on a man's own person is more against his will than that which is inflicted on a person connected with him. Therefore an injury inflicted on a person connected with another is less grievous.
Objection 2 : Further, Holy Writ reproves those especially who do injuries to orphans and widows: hence it is written (Ecclus. 35:17): "He will not despise the prayers of the fatherless, nor the widow when she poureth out her complaint." Now the widow and the orphan are not connected with other persons. Therefore the sin is not aggravated through an injury being inflicted on one who is connected with others.
Objection 3 : Further, the person who is connected has a will of his own just as the principal person has, so that something may be voluntary for him and yet against the will of the principal person, as in the case of adultery which pleases the woman but not the husband. Now these injuries are sinful in so far as they consist in an involuntary commutation. Therefore such like injuries are of a less sinful nature.
