[Scooby-Doo] What drives people to become a Scooby-Doo villain?

There are some cases where the monsters are proven to be real. But why would anyone decide to actually become a Scooby-Doo villain? Who says, "Oh well, I couldn't hack it as an accountant. Time to throw on a lobster costume and terrorize my neighbors!" What is the chain of reasoning that leads people to do that?

It's really quite simple. They know of some valuable resource but aren't able to carry out the extraction so they exploit a local superstition to scare people off. 

It's not entirely unheard of, you know. During the 13th century, Castle Vauvert was a hideout for criminals who faked being ghosts to scare intruders, so convincingly that King Louis IX sent Carthusian monks to exorcise the place.
