There were many cruel things humans used to do. Thankfully, these cruel actions are no longer committed. Even though this Take is "PG"/ toned down, it's not for the faint of heart. Most of the devices mentioned were used during the medieval ages and all the info is from books and the Internet, while the pictures are also from the internet.
1.) Judas Cradle
A torture device that was built like a pointy chair. The victim would be forced to sit on it and it's said that some women would be forced to sit on it with their genitals. The victim's orifice would be ruptured and the victim would die of either impalement or infection since the device wasn't cleaned. A similar device called the "Spanish donkey" was used to torture people. The victim would sit on it as they rode a horse. Weights would be added to the victim's ankles.
A very painful type of torture where the person would be skinned. This cruel practice was used to punish people. Some victims would be put in direct sunlight after they had been flayed so the sunlight would cause more damage to them. The victim would die in few hours or few days of shock, infection, blood loss or hypothermia.
Various cultures would practice the cruel custom of removing the testicles of certain males. Certain societies did this to boys before they hit puberty to keep the boys' voice from getting deep so they could be sopranos. Any victim of this wouldn't develop properly. Once the male reached adulthood, he would look androgynous and his voice would be high pitched.
Alessandro Moreschi was a man that was turned into Eunuch before puberty which prevented his voice from deepening. He became a castrato singer. It's very sad. This cruel practice of making Eunuchs has been abolished in most parts of the world. The video below is of Alessandro singing a song.
4.) Hanged, drawn and quartered
The victim would be hanged without killing them. Then the victim would have their genitals and guts removed and the victim would be dismembered and decapitated. This cruel practice was abolished in 1814.
5.) The breast-ripper
The name is self explanatory, the. Claws of this device would be heated before being used to mutilate a woman's breasts. This cruel torture was outlawed in the 19th century.
A torture device used to crush the victim's fingers and toes, it was very cruel. These were used against slaves in the 1700s. Thomas Clarkson (a abolitionist ) carried some of these to get empathy and help his cause to help slaves. They are no longer used and they are displayed in museums.
7.) Torture rack
A device that was used to stretch people's bodies until their limbs were dislocated. It's no longer used.
8.) Iron Maiden
It was a human sized case that has spikes in it. A victim would be put in as the spikes stabbed the poor person. It's no longer used. There is a rock band named after this infamous device.
9.) Pear of anguish
A torture device that was inserted into a orifice, for women it was inserted into her genitals, for men it was either inserted into the mouth or butt. It would tear the poor victim's skin and/or severely mutilate the victim. It all depended on how much damage the torturer wanted to cause. It's no longer used.
10.) Severing and smashing body parts
Some victims of torture would have certain body parts removed or severely damaged by their torturers. This type of torture is no longer used in most countries.
11.) Burning people
Whether the victim was burned at a stake, burned with boiling water etc, this cruel practice was common in the medieval ages. It has been banned in most parts of the world.
They were common during WWI, WWII and the Vietnam war. In WWII they were used by both Allied and Axis soldiers. These weapons would cause very painful and horrifying deaths. Flamethrowers are such a cruel invention; in the 1980s, new laws would add restrictions on the use of incendiary weapons and Flamethrowers are not used by any army anymore.
13.) Experimenting on people
There were occasions when people were experimented on. The Nazis and Unit 731 are notorious for experimenting on people. The cruel practice of experimenting on people is no longer practiced.
There are many more cruel things people used to do but that's enough for this myTake. There won't be any "sequels."
