Part 1 of a greater list for villains who are pure, irredeemably evil. And yes, I know that there is already a Complete Monster list on this site, but I felt that it had too many "wrong names" on it, so I opted to do my own, more detailed and comprehensive one. Since there are too many names for a 100-item list, I divided it into "sub-lists". This is the first one, for DC Complete Monsters only.

By way of being just as bad as his real-life counterpart. Also noteworthy is the current Earth X version, who molded Kal-El into a loyal Nazi supervillain that Hitler used to conquer the entire world and create a Nazi-run Earth.
The horribly miswritten and character-inaccurate Arrow version, who might as well have green hair, red lips, and be named "Joker".
Attempted to destroy the entire DC Multiverse and came darn close to succeeding. His Green Lantern: The Animated Series counterpart has a similar goal and so also fits.
While he is very much a sympathetic anti-villain/anti-hero in the actual comics, the animated version of the character is this due to his tragic past being downplayed and his villainous and sadistic tendencies being augmented. He's also a pretty big hypocrite too, so you can't even say that he's a Well-Intentioned Extremist anymore. What with casually destroying planets and murdering innocents and all. Really, mainstream Atrocitus would be disgusted with his counterpart.
Arrow version, who instead of a sympathetic, well-intentioned extremist is more akin to a real life African warlord.
The Geoff Johns version, who kills his own family and helps usher in the Blackest Night.
The Post-Crisis, Pre-New 52 version, who killed Aquaman's infant son and enjoyed it. Incredibly, Aquaman still didn't kill the slimeball.
A torture-happy sadist who was so bad that Catwoman (who maintains a no-kill policy) shot him in the head. To be fair, he DID torture her sister and also drive her to madness by forcing her to eat her husband's eyes after Black Mask killed him. Oh, and did I mention he's a self-made orphan too?
Has destroyed countless worlds and civilizations. And the "he's just following his programming" bit doesn't work because Brainiac is shown to have at LEAST human-level sentience, and therefore knows full well that he's doing is wrong, and doesn't care. His status as a Complete Monster extends to his portrayal in DC Universe Online, who fits this for the same reasons as his mainstream version, plus the DCAU version too. Also of note is how both the Pre-Crisis and Post-Crisis versions fit this.
Easily the most psychotic and bloodthirsty of all of the dirty cops to ever be a part of the GCPD. According to Gordon, when he and his "lunatic Gestapo" calmed down a riot, they did so in such a way that they "didn't even leave the statues standing". Branden was also prepared to gun down a man who had taken child hostages, not seeming to care for the latter's well-being at all, and when Batman showed up Branden and his SWAT forces opposed him not because he believed Batman to be a dangerous vigilante, but simply because his activities hurt the corrupt GCPD and their mob friend's business. In fact, during his attempt to take Batman down, Branden resorted to using fire bombs that killed innocent people, something he didn't care about in the slightest. He was also in on the Falcone's plan to use Gordon's wife and infant son to blackmail him. Granted, all of that might seem like small change compared to the actions of say, the Joker, but remember that Branden hasn't had anywhere close to the number of appearances of Joker, or for that matter Zsasz or Black Mask. But he's as bad as he could have been given his limited number of appearances.
