The black death was one of the most devastating disease outbreak in the history of human race. The black death resulted in a lot of crises including religious, social and economic upheavals. Although the disease affected all the people in Europe, at a time the Jews were blamed for the ravages caused by the disease outbreak. The Jews were thought to be responsible for the disease, therefore, other people started killing the Jews who live in their communities and this lasted all through the time of the disease out break.
I'm not sure what type of people exactly, but definitely not something positive considering they cut the hearts out of their victim (while they were living) to amuse them. Hope this helps
