Although the series features countless killers (and non-killers) who committed heinous crimes
without remorse, many of them have a typical motive such as Greed
, or sometimes even a good Freudian Excuse
. Some however, have the (DIS)honor to be called a monster...
- Jacob Lowenstein, from the 1st season episode "Indifference". Using his job as a psychotherapist as a cover to sell cocaine, the man would routinely beat his wife on a daily basis, then watched as she got high on his product and turned her anger towards their children. Beating her six-year old daughter and burning their young son's hands was the only the tip of the iceberg for this woman. Their father did nothing, coming home one night and ignoring the fact that his daughter was unconscious on the floor, with her head sitting in a pool of her own blood. And when she finally succumbed to her horrendous injuries, he tried to get off scot-free by pinning all the blame on his wife.
- Constantin Volsky, the Russian mob boss in the two-parter "Refuge". He ordered an innocent man murdered and dismembered because he had a relative who wouldn't go along with a money laundering scheme. When he finds out that the key eyewitness for the prosecution is a six-year-old boy, he sends assassins to kill him. They murder his mother and an A.D.A. The boy lives, but only because they didn't cut deep enough into his throat. In the second part, he orders the bombing of the precinct where the police protagonists work, just for giggles.
- Leon Vorgitch from "Deadlock" was in prison for killing five people. He then kills two guards and escape from prison. When the detectives come for him it results in even more deaths, including a classroom of children. When Detective Green asks Vorgitch why he killed the kids, he laughs and says "Why not?" In the end he brags to Jack and Connie that he will escape again and kill both of them.
- Rudy Amendariz and Betty Drake from the episode "Wedded Bliss." They run a sweatshop in which their workers (some of whom are literally children) are kept as prisoners and physically abused. When a city labor inspector stumbles onto their crimes, they murder him. Then they murder the two teenagers who witnessed the crime. Then they murder the seven other workers in the sweatshop to keep them from testifying that the other two worked for them. And not only do they show no remorse for their crimes, they show open contempt for their co-conspirator who does.
- Victor Paul Gitano from "Fault" was a sadistic pedophile who lures kids in, then rapes, tortures, and kills them. He doesn't discriminate by gender either. On top of that, when trying to hunt Gitano down, things don't quite go as planned. Not only does he kill one of the two kids he had with him in a subway station full of people by slashing his throat, he almost killed Benson the same way. And then, when they corner Gitano in a warehouse, he manages to get behind Stabler and hold him at gunpoint with a shotgun. Gitano, despite knowing he'd get caught or killed at this point, outright boasts that he killed the other child he had (who was a girl) and bragged that she was a "slut" and a "real little whore" before killing her, even though he never got the chance to molest her.
- Charlie Baker from "Dominance" has murdered eleven people in about a week, after forcing them to have sex with each other first or raping the victims himself. Then he kidnapped two women, killed their boyfriends, and kept them captive on a roof. He's also been raping his little brother and beating his alcoholic father all along.
- Larry Moore aka The Woodsman from "Signature" would use his Torture Cellar to terrorize and torture his victims through every conceivable means which include hanging, burning, maiming, raping and dry drowning them. He meticulously record the sessions, and constantly plays the tapes on a loop to torment current and future captives, and occasionally abduct more than one woman at once so he could have a captive audience and so one victim can listen to another being tortured.
- On a lesser scale than the above, Darius from S9: Screwed, who does his absolute best to ruin the careers and families of everyone in range just to get himself let off for the brutal murder of a woman and her young daughter (which he absolutely committed). And gets away with it too. After it's all over, he tells Ken to "do what [he does]: Feel nothing."
