Evil in the Twenty-First Century

What can we define as evil in the twenty-first century? Paganism had no devil figure, only trickster gods. It was monotheism that personified evil as Satan, although by the mid-twentieth century, Satanism was recognised as an alternative religion with its own churches. Can we point at individuals whose intentions were not diabolical, but the outcome of which had a negative impact? Perhaps such changes can be attributed to an ideology or the rise of science? Or perhaps evil occurs when too many people close their eyes to what is happening around them, while goodness is taking responsibility for the world in which we live?
