If I understand this correctly… Cyclops turned off Wolverine’s healing factor and it turned him into a vampire when bitten. But turning it on means it’ll combat the vampire virus and turn him into a normal mutant again. So why not just leave his healing factor alone and let it combat the vampire virus from the start? Wolverine wouldn’t have needed to become a vampire right?
Unless it’s part of Cyclops’ plan to have Xarus commit all his forces into this doomed assault.
