There are a lot of things you can and can't do on the Disney Wiki, and assuming isn't one of them. We write what is officially according to the Walt Disney Company itself, not what we say or believe. There is no official evidence to support your claims.
Don't you start with the "Neutral, later good/bad" nonsense we always keep trying to prevent. Hans and Bellwether are plain bad, and nothing else. I'd strongly advise that you stay away from infobox editing, at least until you've gain some experience. You end up putting in the wrong stuff.
