"Well, there are two reasons they're trying to kill you and Frisk. The first is that, when a monster absorbs a human SOUL, they gain mysterious, untold-of power. In fact, thats why the humans attacked the monsters. Human SOULS are able to withstand being out of a human's body, allowing monsters to absorb it. But monster SOULS aren't like this. A monster SOUL is too weak to exist out of a monster's body, meaning it shatters as soon as leaving the body."
