Ever seen an angel with horns?

(Sketchbook Edition)
I had this idea because of something Toriel says to Asgore in the final battle of the Pacifist run. She tells him that if he'd really wanted to he could have absorbed the soul of the first human he killed and gone out to the surface to gather the other six. What would the fate of our characters have been if this were the actual story? Toriel divorcing Asgore because she considered him too weak and moving to the Ruins in order to intercept the next human to fall?

(The pie Toriel leaves in the end is poisoned. Just in case it wasn't obvious enough)
