Whether rape is a species of lust, distinct from seduction?

Objections

Objection 1 : It would seem that rape is not a species of lust, distinct from seduction. For Isidore says (Etym. v, 26) that "seduction [stuprum], or rape, properly speaking, is unlawful intercourse, and takes its name from its causing corruption: wherefore he that is guilty of rape is a seducer." Therefore it seems that rape should not be reckoned a species of lust distinct from seduction.
Objection 2 : Further, rape, apparently, implies violence. For it is stated in the Decretals (XXXVI, qu. 1 [*Append. Grat. ad can. Lex illa]) that "rape is committed when a maid is taken away by force from her father's house that after being violated she may be taken to wife." But the employment of force is accidental to lust, for this essentially regards the pleasure of intercourse. Therefore it seems that rape should not be reckoned a determinate species of lust.
Objection 3 : Further, the sin of lust is curbed by marriage: for it is written (1 Cor. 7:2): "For fear of fornication, let every man have his own wife." Now rape is an obstacle to subsequent marriage, for it was enacted in the council of Meaux: "We decree that those who are guilty of rape, or of abducting or seducing women, should not have those women in marriage, although they should have subsequently married them with the consent of their parents." Therefore rape is not a determinate species of lust distinct from seduction.
Objection 4 : Further, a man may have knowledge of his newly married wife without committing a sin of lust. Yet he may commit rape if he take her away by force from her parents' house, and have carnal knowledge of her. Therefore rape should not be reckoned a determinate species of lust.
