These guys eat and hunt children. I don't have a lot of heart for them.
At least not these guys. A demon will have to go through a lot more character development before I start having any feels for their death.
A lion has no concern for the opinion of a sheep. It's in the demon's nature to eat children. Of course we don't have empathy to spare for that from our moral viewpoint, but as far as we know they have no other choice. It's tragic really and while we should and are in fact rooting for the children (even me, even if it doesn't sound much like it) I like seeing the demons, at least the intelligent ones, being presented as emotionally complex. They too experience very human feelings like sorrow, anger and so on. If that doesn't make them somewhat relatable at least, then I don't know.
