Terrorists, assassins, murderers, killers, poisoners, rapists, drug dealers, kidnappers, counterfeiters, robbers, muggers, burglars, thieves, bootleggers, conmen, and little cheats.

Villains like the Corrupt Corporate Executive, the mercenary, or The Emperor and other Lawful Evil villains are per definition not included, even if you may consider them as a kind of criminal.

These characters will tend to be involved with Crime and Punishment Tropes.

Also, don't list more fantastic villains like the Mad Scientist, evil wizards, or Evil Overlords here.
