Crime Sorciere's self-appointed duty is wiping out dark guilds as atonement for their sins. Will they consider their job done and their sins atoned for once all dark guilds are gone?

I can just imagine someone mentioning that to Erza followed by her going on a crusade to wipe out all the dark guilds in Fiore once and for all, so Jellal gives up his resistance.
