When you think about it, Flowey is kind of a zombie; heβs Asrielβs essence infused into a golden flower that was brought back to life using determination extracted from the souls of dead children.
Heβs a double zombie! The essence of a dead child resurrected by the "soul juice" of other dead children.
Alphys accidentally pulled a William Afton.
I haven't really been keeping up with FNAF lore so I'll take your word for it. But yeah, Flowey is the poster child for "came back wrong". Really has tragedy woven into every aspect of his story and yet this mf is like "golly".
