Esta has previously held himself to excel in all of Asmodeus's concerns, of tyranny, slavery, pride, and compacts. He is a 6th circle, after all, and very few priests are; why should he lower himself to specialize? Someday he plans on being Most High, since that is what a proud Asmodean would plan on. Come that day, all Asmodeus's concerns will be his concerns.
Now Esta is far away and Asmodeus is perhaps having trouble seeing him. It's not, in fact, a problem that Esta has ever had before.
Now, the question of which his Lord's concerns are most Esta's own, the question of what might make Esta belong in Hell, is a knowledge-question on whose actual true answer his welfare depends.
