It isn't part and parcel in my experience, and I've played a lot of villains to a lot of casts. There's always been an understanding that if a cast wants a villain they don't make it harder for the villain to play OOCly. Fae couldn't have known that someone had been interested in applying, but if a villain is wanted, souring the soup before they even arrive isn't a good lure.

Even Xehanort would have to work very hard to get things to swing in his favor when there are more than just Terra saying he's a bad guy and stay away, with Sora, Roxas and Aqua all having the same story and chiming in. Finding an advantage, when it's one person's word against three or four well-liked others (five if Axel gets into it), is a hell of a challenge even for an expert. Even an idiot at that point would have to begin wondering if maybe they're not all lying through their teeth just to pick on a "harmless old man". For me, it's not very fun or rewarding if I have to do a lot more work than I would have without the warning going up to even begin to accomplish the same things.

Herd of teal deer aside, I am deterred.
