[Sawrock]

I knew exactly what you meant and still completely disagree. A short list of villains who do work without trying to justify their actions:

Bowser from Mario (he openly claims he’s a bad guy and loves to roughhouse; he’s basically a bandit king (or known as Demon Lord Bowser in the east)

Frieza from Dragon Ball Z (completely selfish and prideful, yet people love him for his higher-than-thou attitude (as opposed to holier-than-thou))

Ryuk from Death Note (could be considered more of a trickster but to be frank he toys with people’s lives for fun, and simply just that)

King K Rool from Donkey Kong Country (leader of his kremlings through sheer strength, wants to eat the Kong’s banana hoard even though he hates the taste of bananas simply to deny them their bananas)

Giovanni from Pokémon (simple and effective: mob boss who takes what he wants because he can)

All of these characters have depth, but none of them justify their evil actions- they’re rotten because they are, and thus as you put it, cartoonishly evil. They’re still great because they’re still characters with plans and hopes and dreams... just ones that are self-awareingly selfish.
