AuricGoldfinger is such a memorable and witty villain that you almost forget that he's a criminally insane maniac. His plan involves poisoning an army barracks and the surrounding town - 60,000 people (he shrugs this off with A Million Is a Statistic) - and then detonating a nuclear device in Fort Knox to trigger a major economic crisis for his own profit. He considers such a scheme potentially one of the greatest achievements in human endeavor, up there with scaling Everest and splitting the Atom. He punishes his assistant, who becomes a Bond girl and costs him a rigged card game, by having her murdered with golden paint. He tries to have James Bond ''sawn in half with a laser'', and he gloats to his mob partners even though he always planned to kill them (and does) - he just wanted to let them know how brilliant a criminal mastermind he was. Bond panders to his ego because he sees just how dangerously mad he is.
Moonraker: Hugo Drax is a cold, snobbish, understated Control Freak who wishes to exterminate the human race. He has enough of a God complex to engineer a plan to wipe to wipe out humanity, build a secret billion-dollar space station and claim that he alone can credit for it, and tell his crazy Nazi space-cult that future generations will look up and "know that there is order in the Heavens" after their insane Evil Plan is completed. Drax gives you plenty of reasons to hate him throughout; setting his dogs on his assistant Corinne is probably one of the nastier moments in the series. Indeed, the sheer scale and horror of his plans combined with his utter lack of redeeming features just might make Drax the single most evil villain in the entire Bond franchise; he certainly has the most terrifying scheme to date, and he is one of the least likeable bad guys overall, both for his cold Smug Snake attitude and for the fact that his explicit reason for not simply shooting the secret agent (and presumably, for every other person he has killed in gruesome ways) is that he wants Bond's death to amuse him. A truly nasty piece of work through and through.
Licence to Kill: Franz Sanchez can be charming, but he's also uncommonly brutal and ruthless in dealing with his enemies or those he perceives as disloyal to him - he brutally whips his mistress, Lupe Lamora, with a stingray-tail whip as a punishment for infidelity. It is also implied that under his orders, his top henchman Dario removed the heart of the man she has slept with. He feeds Bond's best friend, Felix Leiter, to a shark (he had his newlywed wife raped and killed right before), and he kills one of his collaborators, locking him in a decompression chamber, believing he stole his money. Towards the climax, he also decides to start "cutting overhead" and shoots his financial advisor.
Tomorrow Never Dies: Elliot Carver is a media mogul and head of the Carver Media Group Network. The actions of he and his group range from the merely unethical (releasing software with bugs in order to require constant updates); to libel (releasing stories about mad cow disease involving a British beef baron who lost money to Carver in poker and keeping those stories running after getting paid by the French); to blackmailing the President to sign a bill (and releasing the tape anyway); to causing "floods in Pakistan, riots in Paris and a plane crash in California"; to murdering his wife when she gets too close to Bond; to ordering the brutal torture of Bond and Wai Lin by his dragon, Torture TechnicianRichard (goes by Mr.) Stamper. His most heinous acts involve sinking a ship and killing the survivors, sinking a Chinese jet, and attempting to using a stolen British missile to destroy Beijing, leading to World War III; all of this is so he can gain exclusive broadcast rights in China. Already a wealthy man, Carver is willing to cause millions of deaths just to satisfy his Greed.
Quantum of Solace: General Medrano raped and killed Camille's family in front of her, and burnt down the house. He conspires with Dominic Greene of the organization Quantum, deliberately engineering a nationwide drought in Bolivia to get allow Quantum to get its hands on his nation's water supply and having the gall to frame the government for selling off its rainforests. Medrano is willing to plunge his nation into drought and famine, dooming multiple innocent people, just so he can have an excuse to seize power. When Greene informs Medrano how expendable he truly is to Quantum, Medrano buckles under pressure and acquiesces to Greene's demands before trying to rape his maid out of frustration. When Camille intervenes, Medrano tries to rape and murder her as well, mocking her about her mother and sister.
Moonraker: Though his plan is smaller in scale than his film counterpart's, Ian Fleming's original version of Sir Hugo Drax is no less vile. Born "Hugo von der Drache" in Germany and an avid fan of Hitler, Drax ran undercover missions against Britain for the Reich until he was mistakenly wounded by his own side and nursed back to health by the British. Stealing the identity of a MIA soldier with a similar name and feigning amnesia, Drax murdered the first rich man he could find after leaving the hospital for startup money and began plotting to avenge Nazi Germany's defeat. Using his family's holdings in rare metals, Drax paid out of his own pocket to design the Moonraker, a state-of-the-art nuclear missile meant to defend Britain from the Russians, with Drax's philanthropy elevating him to a national hero. The only problem was, the missile was set to destroy London on its first test firing with a real atomic bomb. When Drax describes the intended death toll for this catastrophe to him, Bond, a hardened killer himself, is left almost catatonic. Other crimes include running a motorist off the road and over a cliff due to the mere possibility he might've been a spy, and having people tortured for information with welding torches. For Drax, the mere destruction of their greatest city was not enough; he made himself into the British people's greatest hero just so their collective spirits would be crushed when the nuke hit.
