If the title is not a typo and you want a blaze of Gory then...
The Red Cap for being a scum-sucking, self important, evil asshat.
Cowl and Nick for trying to end the world on Multiple Occasions.
Shagnasty for being the most evil being on this list.
Rudolf for being... well Rudolf.
Lord Raith, so I don't have to hear more theories about him coming back even though he was a boring villain
Oh, and Butters.
