Dr. Doofenshmirtz. He is always there for his daughter.

Dr. Heinz Doofenshmirtz

He is actually a really good dad throughout the show.

Literally Satan.

Among his greatest sins: trying to be a bro and let Adam and Eve know that they were naked in some perv's garden

Edit: come to think of it, it's not entirely accurate, as I don't think Satan ever claims to be evil. But there's a lot of anti-Satan propaganda in the Bible.

Megamind. Dude raised in prison and bullied his whole life, he just want attention from Metroman. Once he got the attention of Roxanne the act basically stopped.

Luci

The Mighty Monarch.

Gru

Character that insist is evil but clearly isn't: Crowley from Supernatural.

But I think that character that is actually evil but still charming is more interesting, and for that I bring forward Baal from Stargate.

Since my usual suspects are already mentioned, I'll go a little more esoteric - ProZD's "a villain who always does unintentionally helpful things" - https://youtu.be/GPUgjy-Pn-4

Professor Chaos

The Brian, otherwise Pinky wouldn't stay with him.

Well, he never says he's evil but is certainly seen as a villian: Dr. Victor van Doom. He's actually glimpsed all possible timelines of humanity and only the one where he reigns is not ending in destruction. https://qph.cf2.quoracdn.net/main-qimg-4d9668819558c73a8fda43cd4bc0ef0a-lq He is also loved by the people of the country he does rule. And when he had indeed managed to rule the world, it was a time of peace. I mean, mind control peace (he amplified the power of Kilgrave the Purple Man) but still.

If you're asking yourself why Kilgrave didn't simply control him, Doom is one of the few people with so much natural willpower that Kilgrave's powers don't work on him: https://i.pinimg.com/originals/d5/e8/c8/d5e8c8ee71120993b8616128b08a6a22.jpg

I Scream from Chikn Nuggit.

Claims to be the epitome of darkness; was exiled from Hell for falling in love with an Angel named Fwench Fwy.

Vegeta

Melkior/Morgoth, they saw that Arda was a deeply flawed creation and attempted to correct it before existence was sung into being.

After the fact their actions are certainly viewed as evil by the world they tried to change but had the rest of the Vala joined his song the world simply would have been different, not worse.

Elphaba from Wicked.

Dr. Cortex is undoubtedly evil; but he MASSIVELY overexaggerates just how much of an evil genius he is. The worst thing he did (other than building a slave army from endangered native creatures) was shoot an emu one time. Most of the other bad things he did were more incompetence than malice

I know hating on League is in vogue in some corners of the internet, but I really like Veigar. He claims to be the master of evil but hates that nobody takes him seriously because he's short and he takes umbrage with that. His voice lines are quite fun.
