For me it is smurfs! There is nothing more evil. Stomp them into pulp, scoop up their blue blood and squishy insides and serve it all as a sweet blue fruity drink. When people comment on how tasty and refreshing the sweet blue drink is, you can smile as you glance at look the little caps, pants, glasses, etc, on the sole of your boots-- especially, if the person you served the drink loves smurfs.
Oh, wait! I meant to write that, yes, hordes of goblins, skeletons, zombies, minor demons and devils are fun to kill.
