Fun fact: when a Stern Ritter's epithet is revealed, they soon die. Quilge Opie of the Jail? Cut in half by Grimmjow. Driscoll Berci of the Overkill? Incinerated by Yamamoto. The Roar, the Question and the Yourself? All toast, courtesy of Kenpachi. And the second Yourself was annihilated by his majesty Yhwach. Now is Bazz-B's turn, heh heh heh. He may squirm for a little longer, but his fate is sealed already.

I guess that's also why As Nodt is still alive. Even though it's obvious he is the Fear, it hasn't been stated officially yet. He gets to live until he is stupid enough to reveal what his F means.
