The Butcher Redeemed is the Iki Island trophy for freeing the whole island. You must defeat the Eagle in the story and clear every Mongol territory there.
Liberate all 6 Mongol territories on Iki, then finish The Blessing of Death. Do the bases first to also get the mask.
Liberate all six bases before the final duel of The Blessing of Death. That way you also earn the Mask of the Eagle.
