Oh, I see. Good question! Given the intentional parallels between the forced transformation and possession by extraplanar entities, I would think a druid, for example, would view a lycanthrope as a person possessed by an animal spirit. They might be inclined to seek a way to appease, calm, or banish the spirit as a method of alleviating the turmoil both the humanoid and the spirit must both be in. That’s a potential plot direction I would be happy to have eventually lead to a viable cure. On the other hand, something like a polymorph-focused wizard might view the lycanthrope as some sort of arcane anomaly, maybe a strange form of Sorcerer struggling to control their magic. Especially if the lycanthrope inherited the curse from their bloodline.
