"Talmudic Rabbis Debated the Cost of Rape—In Terms of the Woman’s Market Value"

"Ketubot 36b, where the mishna says that the fine is not paid by “one who has intercourse with a convert or with a captive woman or with a gentile maidservant.” Each of these women are presumed to have been unchaste, and so their reputation and marriage prospects can’t be further harmed if they are raped."
