Gnorga, the Queen of Trolls in A Troll in Central Park, even goes so far as to sing a Villain Song about what a nasty person she is and how much she enjoys it ("It feels delicious, to be so vicious, I'm Gnorga, the queen of mean!"). When she explains why she hates Stanley so much, she angrily complains "He is kind, he is good, he is gentle...and, he is giving a bad name to trolls everywhere!"
Mad Madam Mim in The Sword in the Stone. She sings a whole song about how wonderful it is that she's proud to be mad and evil, and she takes "terrible" as a compliment (and finds it lovely when someone's sick—though she doesn't find it so lovely when she gets sick later...).
Aladdin's Jafar doesn't carry quite as big a card as Maleficent, mainly because The Grand Vizier can't actually say he's evil (though he ALWAYS is), but he doesn't seem to take offense when called "Your Rottenness" or "Oh Mighty Evil One" by his parrot and...calling him a snake leads to an epicInsult Backfire.
The Chief Blue Meanie in the movie Yellow Submarine insists that his minion Max never say "yes". Because "we Meanies only take 'no' for an answer", and gets extremely angry at the sound of the word "yes", even when being answered in the affirmative. Sometimes, his own aggression gets the better of him and he needs to be revived with "nasty medicine", which makes him even more eccentric than he already is. He encourages his army of Meanies to be as unpleasant as possible, but later admits that his cousin is "the bluebird of happiness".
The Chief subverts his "No only" order moments later when he summons the Flying Glove:
Chief: Come here, Glove. Look out there and what do you see? Tell him, Max.
Max: Someone running, Glove.
Chief: Yes. But you'll soon put a stop to that, won't you Glovey? Go, Glove, point and having pointed...pounce, go!

In A Nightmare on Elm Street, Freddy Krueger absolutely revels in his work, perfectly happy to acknowledge how sick and twisted he is. However, he is after revenge for the vigilante justice he received, so he does have some delusions of justice. Though he eventually did succeed at his Ghostly Goals...and continued killing anyway, since, hey, it's fun, and just because his revenge is complete, that doesn't mean he can't just go on slaughtering.
At first it seemed that way. Then Freddy's Dead: The Final Nightmare revealed that he had an agenda against all the parents of Springwood for lobbying to have his daughter taken away from him for her own safety, and he wanted to get back at even those parents who weren't among his killers by taking their children away from them. And then in Freddy vs. Jason, a character mentions, contrary to Nancy's assessment in part three, that some of the kids of the town still are related to his killers. You see how it goes.
Freddy doesn't need a reason to kill. He's a total monster. Any reason he may have, he might give, well, that's just incidental.
In this case, it might be due to the fact Freddy gained his powers thanks to making a Deal with the Devil with some dream demons. So considering who he's working with, it's kind of justified.
The Djinn of Wishmaster is patently aware that he is pure evil. He states he can't be undone because his presence perpetuates evil in the world and his Badass Boast to Alexandra when she wishes to know what he is is equal parts horrific and illuminating.
Djinn: You wish to know what I am? To you, I am this: The cry of the abandoned child. The whimper of the whipped beast. I am the face that stares back at you from the shadowed mirror. The hollowness at the heart of all your hopes, Alexandra. I AM DESPAIR.
Parodied with Dr. Evil in Austin Powers, who went to evil medical school and is disappointed that his son wants to be a non-evil veterinarian...or perhaps work in a petting zoo.
Dr. Evil: An evil petting zoo?
Scott: You always do that! (Storms off)
Later in the movie:
UN Representative: Mr. Evil-
Dr. Evil: DOCTOR Evil. I didn't spend six years in evil medical school to be called 'mister' thank you very much.
Mr. Freeze in Batman & Robin, who even shouts "Kill the heroes!" It is also worth mentioning that his only non-ice-related pun in the whole film, if memory serves, is the one identifying himself and Poison Ivy as "Adam and Evil".
Freeze's case is particularly troublesome, as he gets the sympathetic background that could make him an Anti-Villain.
While not the main villain, or even doing anything horrendous (when you take the film's nature into consideration), some of Fat Sam's goons in Bugsy Malone proudly sing about just how rotten they are in the aptly named song "Bad Guys".
In the 1987 Dragnet movie, the villain heads the organisation P.A.G.A.N. - People Against Goodness And Normalcy. However, it's a bogus group intended to get the populace riled up about having card-carrying villains in their midst.
The 'cult' (see The Other Wiki) film Evil Roy Slade features this in spades. He even yells at one of his henchmen who stays loyally at his side when the law offers a reward for him. Before that operation, he goes over the basics for his gang: 'Sneaking, Lying, Arrogance, Dirtiness and Evil. Put them all together and they spell "Slade!" '
Jean-Baptiste Emanuel Zorg from The Fifth Element is a great example, though he tries to justify this behavior by claiming that life comes from chaos and, therefore, destruction actually creates and improves life.
In Hudson Hawk, when Hawk asks Big Bad Darwin Mayflower who he is, Mayflower shoots back, "Isn't it obvious? I'm the villain."
In classic James Bond movies starring Sean Connery, the top villains are brought together by an organization named SPECTRE - that stands for "Special Executive for Counter-intelligence, Terrorism, Revenge and Extortion".
Oba from the second ''Female Prisoner Scorpion'' film, Jailhouse 41. She's very quick to exaggerate her own badness compared to the legendary Sasori (the titular character), but her crowning moment of evilness is the point at which she outdoes all the other women present in describing the crime for which she was imprisoned: she drowned her two-year-old son and then stabbed her unborn baby to death, because her husband had an affair. She hikes up her dress to show off the scars...and keeps it up and in everyone's face for what seems like an eternity. She absolutely embraces this persona and the fear it engenders in almost everyone, and ultimately dies still muttering about going back to her home island, burning down everyone's house, and stabbing them all.
In Kung Pow!, Betty is the loyal enforcer of the Evil Council. And there's also the fact that he is formally known as Master Pain.
Mayor: Master, what exactly is the Evil Council's plan?
Benedict in Last Action Hero knows he's a villain and has no problem showing it. Of course, he's an actual villain in the Show Within a ShowJack Slater IV. Once he gets out into the "real world", he realizes it works by different rules (such as the cops not showing up immediately after he shoots a random guy on the street, and the neighbors not caring) and tries to subvert many villain tropes, except, of course, for the Evil Brit, the Evil Is Hammy, and the Evil Gloating ones (he can't exactly help the former, and the other two are too ingrained into him). He's played by Charles Dance, who also played the card-carrying Big Bad in The Golden Child.
Benedict: Gentlemen. Since you are about to die anyway, I may as well tell you the entire plot. Think of villains, Jack. You want Dracula? Dra-cool-la? Hang on (takes out the magic ticket), I'll fetch him. Dracula? Huh. I can get King Kong! We'll have a nightmare with Freddy Krueger, have a surprize party for Adolf Hitler, Hannibal Lecter can do the catering, and then we'll have christening for Rosemary's Baby! All I have to do is snap my fingers and they'll be here. They're lining up to get here, and do you know why Jack? Should I tell you why? Hmm? Because here, in this world, the bad guys can win!
In the 1998 Lost in Space movie, the main antagonist, Dr. Zachary Smith, does it several times:
Evil knows evil.
Let me tell you a lesson about life, kid. There are monsters everywhere... I know, I am one.
In that case, it was more because Jack was being pragmatic than evil. As he points out later, the only things that matter in the world "are what a man can do and what a man can't do", and points out that if he'll die in fair combat, "well then, that's not much incentive for me to fight fair, now is it?"
Phillip: You are killing her! Blackbeard: I'm a bad man.
Bluto in the Popeye film, who has a song number boasting of his being mean.
In Prisoners, Holly Jones is revealed as one of these, doing what she does (kidnapping and murdering children) to "crusade against god."
Lampshaded and then fully embraced by Tony Montana in Scarface in the restaurant scene.
You're all a bunch of assholes, you know why? You don't have the guts to be what you want to be. You need people like me! You need people like me so you can point your fucking fingers and say 'That's the bad guy!' What that make you? Good? You're not good. You just know how to hide. How to lie. Me? I don't have that problem. Me, I always tell the truth. Even when I lie. So say goodnight to the bad guy!
In Star Wars, the Sith philosophy can be summarized thusly: 1.) The practicing individual is unfettered by any sort of conventional morality, laws, or system of ethics. They can do whatever they want, indulge in every vice, and commit unspeakable crimes (and are encouraged to do so by the texts themselves); and 2.) The imposition of a dictatorial system of government which muzzles the populace, crushes dissension, and reduces the people to a near slave status.
As noted above, Gene Hackman's Lex Luthor in the Superman films proudly declares himself to be "the greatest criminal mind of our time!"
The main villain of Time Bandits is the embodiment of evil and referred to simply as "Evil". It's interesting to note what the screenwriters consider evil. He's obsessed with efficiency, technology, and work. At one point, he laments feeling "good", and his minions sympathize.
