I don't believe in souls, I believe in the Continuation of Existence. This is Perfect Storm just making copies of a now dead Taylor. If Taylor's consciousness imprint somehow overwrote Perfect Storm's personality then I would be more accepting to a copy being the original through Bodysurfing in the same way Dr Bright does with
SCP-963. It's why I specified using the Ship of Theseus given that a copy of the ship, when the original ship is still there, even when destroyed, is still a copy of the ship not the original, but a ship with every part replaced is still the original ship solely due to it's existence. In this case Perfect Storm would be taking the name plaque (Calamity Witch/Taylor Template) from the now destroyed original ship (original Taylor) and remodel (Bonesaw level Body Horror) another preexisting ship (Random Nobody) to look like the original ship and glue the name plaque on the copy ship (copy Taylor that's actually the Random Nobody), the copy ship is still the second ship but now looks like the original and is named the original but in the end it's not the original (well, unless Taylor subscribes to cannibalism, gains her body, and eats her own brain to gain her original strength/consciousness/existence! (


D I Joke! I'll only think of her being 50% of the original.))
TL;DR:
Think Causality using the Concept of Consciousness (not the Consciousness itself): Continuation of Existence.
From brain to chip to new mechanical/digital body and vice versa, even multiple copies. But PS only has what it thinks is Taylor, just as it had what it thought was Calamity Witch. It isn't Taylor making the decision to live.Your brain is You, your existence is who You were, copying yourself into a new body makes both you because you did that but the first the Original and the second is the new Original but will never be the original Original unless it was a perfect transference right down to the atoms. It's why I prefer either brain-in-jar or nanites body-to-metal conversions for Transhumanism.
