Idk if it should be taken literally but in one of your ask where you mention Sans retains part of his sanity becuase he seperated himself from his soul, does that mean he actually seperated his soul from himself like what Kris does by the end of Deltarune?

No <3 his soul is technically still part of him; he’s a monster, he can’t live without it. It’s less literal and more figurative… more in the way he explained LV to us all, once upon a time.

The more you kill, the less it hurts. And he’s killed so much he can’t feel a thing.
