"Tarnished" definitely isn't the right word . If being a person of principle--who is willing to act on those convictions--is a fault, perhaps we could use a bit more tarnish. IMO the only real downside to the Fredmen's Bureau is that it was allowed to languish.Tarnished might not be the right word. Because he was a religious abolitionist and head of the Freedmen's Bureau, he was hated by enemies of emancipation and reconstruction. Maybe still hated now by some for similar reasons.
