We can put Erza and Kagura out of the equation, they are out of commission. Actually the reason why i ask this is because the title "Sin and Sacrifice", made me thought of two scenarios, Ultear's sin of attempting to kill Rogue and Frosch's sacrifice to save him. Or Jellal's past sin and sacrifice to atone for it. And yeah Mashima did create Jellal as a replacement for Sieghart, hell he even created 2 Jellals.
