Free Dictionary states that one of the definitions for 'opprobrium' is
Disgrace arising from exceedingly shameful conduct; ignominy.
Dictionary.com states it means
the disgrace or the reproach incurred by conduct considered outrageously shameful; infamy.
What I'd like to know is, who feels disgraced when using the word 'opprobrium'. Is it the person who does the shameful act, or do those who know of the shameful act committed by another feel disgraced?
