“Georgia Tann. She ran the Tennessee Children's Home Society and helped a lot of Hollywood stars adopt babies. In order to keep up with demand, she would train people to pose as nurses and they would steal newborns, telling the mothers their baby had died. She and her employees also used threats of legal action to procure children, they would go to nursery schools posing as welfare agents in order to kidnap children, and they would adopt out children who were only supposed to be in the children's home temporarily.

While in her care, Tann mistreated her charges and there are reports of murder through neglect. She would use bribes to get away with it but eventually, the law caught up with her and the Children's Home Society was closed in 1950. She died of uterine cancer, the same year the home was closed. I sincerely hope she suffered.” - Applesintheorchard

“Anders Behring Breivik definitely takes the cake for me. Blew up a bomb in the center of Oslo. Meanwhile went to an island where a political youth gathering was taking place.

“Those Japanese soldiers who made "Comfort Women" and used women as sex slaves, and tortured them when they ran away. A prisoner who tried to run was tattooed, tortured, or killed. In one case, a head was severed and boiled, and the soldiers made some of the other slaves drink the liquid. And the cover-ups thereafter - how these women were prostitutes, how these men didn't exist. As if. And recently, some group made these women into figures and mocked them in disgusting ways.” - Moomting

“Adolf Eichmann, he basically was the brain organizing Hitler's Holocaust. You need the logistics for the camps, the trains, and industrial levels of murder done? Eichmann was the guy. He fled to Argentina, got caught by Israel, and was trialed in Jerusalem. He is until now the only person to receive the death penalty by an Israeli court.” - foxtrottbravo

“Henry Kissinger. Along with all the genocides he aided in, the bombing campaigns that irreversibly damaged Laos and Cambodia, and Vietnam, and the mass implementation of wire taps, he also committed treason with Nixon in 1968. Kissinger was likely to be Secretary of State for either Nixon or Humphrey and actually preferred Humphrey. However, just to be sure he got the gig, when he got wind that LBJ was offering to halt bombing operations in North Vietnam to get them to the table for peace talks, he went to Nixon and informed him of the potential deal to get in good with Nixon.

In response, Nixon opened up back-channel communications with South Vietnam, and informed them that this was the offer LBJ was making. Naturally, South Vietnam didn't want a halt to the bombing and pulled out of peace talks. LBJ didn't get a peace deal that would have assured Hubert Humphrey the presidency, and Nixon got the chance to be the guy that ended the war. In doing so, they also extended the war by 7 years and got millions more people killed. The LBJ administration discovered this and decided not to prosecute the Nixon administration or Kissinger because they feared it would lead to a 'crisis of faith in the American Government' if the treason became public.

So, the war was extended just so Nixon could get elected. The worst part? Kissinger wasn't even privy to the actual conversations being had between LBJ's white house and the North- so he did all of this off of assumptions and educated guesses. Again, just to get a gig that was his second choice” - CommercializedPan
