First - no one is 100% evil. Name one decent character in all of fiction that is 100% evil without a hint of humanity or at least an understandable point of view.

100% evil is boring and 1 dimensional.

Second - they've not turned them into anything yet since the show hasn't aired. You're going strictly based on spoilers.

Plus - we know any "love interest" is simply to infiltrate the Scooby Gang so the impetus is dishonest at least and could indeed be evil.

If you're going to develop a head canon based on little or no information you should probably fantasize about something you like.
