this is entirely a crackpot theory as I haven’t reread all of dgm in ages, so I’m likely missing a lot of relevant information, but:
is the reason for the earl making akuma to prevent new accommodators? Like, if I’m interpreting past!lavi’s words correctly, innocence feeds off of/attaches itself to people of particular suffering and tragedy, right? And mana won’t let himself grieve/cry because it will attract the earl (I think) and Allen is the same. So is the earl intentionally going after people who experience great suffering and just… nipping them in the bud? if the innocence is hostile, or even just keeping in mind the Noah clan’s hatred of it, then preventing it from getting stronger from feeding or gaining the ability of fight would be a smart move.
I’m not sure why specifically going after people in deep grief is a qualifier outside narrative themes, but it would make some sense to me, especially if the Noah’s past world was destroyed due to something relating to the innocence.
