Oh, I don't think Malik killed her or anything similar, even if he is actually on space right now after their encounter, I'm almost sure Aglaecwif is on the same tier of danger than Indra and a full power Valravn, she wouldn't be killed off screen, in fact, seeing how mentally unstable Malik is, since he apparently still hold human values and moralities(which given the lvl of corruption he must have, is probably nightmare) I've been thinking that he might flip sides, like, Aglaecwif is a Monster, as bad Dexter and Bramon are, she's straight up a Monster, but, at the same time, she does genuinely love her Children, and is certainly a manipulation master aside her Fantasy Trait, she might be able to swing Malik to her side, someone with beliefs so extreme and a high regard for family dynamics, that would bring into play a third party(since Glae clearly isn't that loyal to the Apostles) with actual power, could even be a way to take Bernhardt out of the Story while reserving a Full Incarnated Apostle to Henri, an hypothetical traitor Malik with Aglaecwif as support could probably be enough to kill Bernhardt, or hold him indefinitely on a fight, making things more bleak to everyone else on Earth.
