At first I though Rogue was going for the "sacrifice one person to save millions", but with what he said in this chapter about not caring for live and killing Sting that makes no sense anymore.

That Ancalogia would accept an "insect" as his subordinate seems rather unlikey to me, but maybe he joined Zeref's faction, whatever they might be planning to do. Or there might be some other faction out there who havn't revealed themselfs yet.
