Nowadays rape actions are one of the main problem of society. You can be faced with these kind of situations in everywhere from West and North to East and South.
I did some researches about most insane rape criminals that went down to the history. Here are the top 10 shameful moments of humanity:
Belgian girl died after being raped by Africans (Italy):

The woman, who eventually got away from the gang that abducted her, says her captivity lasted for two months in early 2017. This comes on the heels of reports about an Italian girl who died after being drugged and raped by a group of illegal immigrants from Africa.
Six Tunisians have been accused of kidnapping a Belgian woman in Italy and subjecting her to sexual slavery.
Evil stepfather, 41, raped his stepdaughter 1,800 times (Australia):

A man from Kingaroy, northwest of Brisbane who raped his stepdaughter 1,800 times from the age of 10 and then beat her when she fell pregnant has been jailed for 15 years. The court heard the 41-year-old man started violating the girl from the age of 10 over a six-year period, until the victim ran away from home at age of 16.
During the six-year ordeal, it's estimated he raped her 1,800 times, and after getting her pregnant, he bashed her in an attempt to make her miscarry, the court was told. But even after the teenager gave birth to the man's son at age 15, he continued to rape her - often in front of the newborn child - in the family home.
Eight men have been charged for the gang rape of a woman (Sweden):

Eight men have been charged for the gang rape of a woman in December. Swedish crime experts say this type of attack, with so many attackers, is rare in Sweden. The charges say the rape was particularly brutal because the men held the woman in place by her head. They also covered her mouth to prevent her from screaming as they repeatedly attacked her in a Migration Authority residence.
The Swedish Crime Prevention Council says that one in ten reported rapes are a gang rape, but the most common form is two men raping one woman. "That there is this many assailants is extremely rare," researcher Martin Grann said to the newspaper Aftonbladet.
When the woman called emergency services after the attack, she said she had been raped "all night".
Murder of Oksana Makar (Ukraine):

The murder of Oksana Makar took place in March 2012 in Ukraine, garnering extensive media coverage both at home and abroad and leading to mass protests. Oksana Makar, aged 18, was attacked by three men in the city of Mykolaiv on 8 March 2012: she was raped, strangled, set alight and left to die, though she survived another three weeks after being taken to hospital. Her case became a cause célèbre in Ukraine when only one of the attackers was charged by the police. The other two, whose parents were reported to be former government officials, were released on police bail, allegedly because of the personal connections of their parents. They were later rearrested after a public outcry and mass protests on 13 March. Protests demanding justice, to gather funds and encourage blood donations continued after the arrest as well.

According to the indictment, Ahmet Suphi Altındöken drove Aslan to a wood after all the other passengers had got off the bus and then tried to rape her. The young woman fought back using pepper spray but Altındöken then bludgeoned and stabbed her to death, before being helped to dispose of her body.

Shortly after midnight on Wednesday, 20-year-old Michel Brasil da Silva uploaded a 30-second clip to Twitter, accompanied by the words: “They smashed the chick. Do you get it or do you not get it? lol”. The clip showed an undressed, unconscious woman lying on a bare mattress. She was being filmed by two men, both fully dressed, who took turns manhandling and mocking her.
“This one just got knocked up by 30 guys,” one of them says. “Check out the state she’s in. Bleeding,” says the other, directing the camera toward her visibly injured genitals. At one point, the man positioned his head next to the unresponsive woman’s buttocks, stuck out his tongue, and took a selfie.
The footage set off a firestorm on social media and brought national attention to the reported gang-rape of a 16-year-old by as many as 33 men in Rio de Janeiro over the weekend — a crime the police had no knowledge of until social media users contacted them en masse.
