We're talking villains with no goal but to destroy. A simpleton villain. There is normally nothing to that sort of character except a crazed killer. They are, in general, shallow and not memorable unless they pull off some entertaining fights (like Kid Buu). I don't know about them being less likely to disappoint, but I don't expect much of those sorts of villains in the first place. It's not that I don't like villains like that, it's just that they are not the best type of villain IMO.

I prefer villains with some substance.
