Kris surviving temporarily and acting without their SOUL makes sense based on Flowey's account in Undertale. Kris's body would naturally contain their "essence" or "will," and it could be animated by residual Determination, similarly to how "Asriel" was "resurrected" as Flowey when the flower infused with his essence was injected with Determination. Kris wouldn't immediately revert to an amoral sociopath without their SOUL, even if they can't feel love without it they still know how they should feel and act, and they also don't have any of Flowey's looper megalomania to detach themself from their situation.
That's just explaining how Kris acts when they rip us out though, Kris ALWAYS being without a soul doesn't make any sense.
