You guys really need to start thinking about the effects a human soul would have in close proximity to a monster. And I'm not taking about the fusion of human and monster souls to become a god, though it's definitely a point I'm making. A human soul has the ability to grant a monster with godlike powers, how is it that people are able to write or draw anyone nonchalantly holding a soul OR FRISK'S. There should be some strong sense of greed when around a human soul. Like the monsters psychologically get twitchy with their hands or claws or whatever, or they can't stop looking at it. It would make sense Asgore would have a strong sense of will to not be affected by it since he fought in THE WAR. Simple monsters like Sans (though he would manage somewhat well) or Alphys or Mettaton should get some sense of greediness when Frisk or any other soul becomes exposed because that is some pretty powerful stuff and it can be easily snatched.
