Designated Villain: Krudsky is treated like crap by both the gang and Fairy Princess Willow even before he does anything villainous. In fact, it's this that motivates his evil plot in the first place. Yes, he was a Jerk Ass, but even so...
Apparently he was treated like crap all his career, and Scooby and Shaggy's payback was the last straw. Making him a Jerkass Woobie.

Is this a direct statement or saying that only monstrous versions of fans would ever on purpose attack Scrappy? In this situation he would have been the innocent victim, well played writers, well played.
