1. The Black Death occurred from c. 1346-53, and other plague outbreaks occurred later, notably in London in 1665-66.
2. If you look at the estimated trend for homicides, there is a long-term decline starting around the end of the Middle Ages and early Modern period, but the historical record gives accounts of many periods of civil unrest and violence, warfare, and lawlessness. There were many, many peasant revolts, crop failures/famines, and invasions or wars which saw widespread atrocities and loss of life and property.
Again, at least read a bit about the period you claim to know so much about. Pre-industrial Europe was far from a strict, unfaltering law-and-order state creating some domesticated Ubermensch.
