No, they shit on it because it's requires like three gigantic leaps in logic to come to that conclusion.
1. That Dracula's Caslte is multiverse, and not just a single living entity that can manipulate space/time (which is explained in the fucking games)
2. That defeating Dracula is the same as destroying the Castle, even though the former merely triggers the latter, and
3. That defeating Dracula is a direct feat of raw power, and not something the Belmonts can do in large part to the Vampire Killer being a direct counter to Dracula.
