I would really like it if Asutsuo roamed from town to town, resurrecting people. Then we would read what happened to those people like in the earlier chapters. And like chocolate chapter, we could get parts of him, know him better. Manga ended like "you're not just a Necromancer" but then again, it didn't give anything beside "necromancer". If you intend to give a meaningful message, which I think is quite acceptable, robbing him from his precious identity and creating a new one hasty is not the way.
Like I said many other times, sight of Sid is enough to sicken me to death. I bet Sids' mother was so ashamed to give birth to this rotten creature and committed fucking suicide. Shame she couldn't predict this before birth, sad emoji for mother : ╥﹏╥
