Taint is used for corruption and for disgrace. If therefore we take the oldest reading it may be reformed thus:
—sure her offence
Must be of such unnatural degree,
That monsters it; or you for vouch'd affection
Fall into taint.
Her offence must be prodigious, or you must fal1 into reproach for having vouched affection which you did not feel. If the reading of the folio be preferred, we may with a very slight change produce the same sense:
—sure her offence
Must be of such unnatural degree,
That monsters it, or your fore-vouch'd affection
Falls into taint.—
