It's become basically impossible to deny at this point. They've been evil for the better part of a decade, but at this point they're actual death-worshiping cultists. They're the type of bad guy you put in a movie because they're so obviously bad guys and you don't want to waste time explaining that they're evil. Most people see sadism and grave dancing and instinctively know "I am looking at evil right now".

They made the mistake of not couching their evil in feelgood newspeak. It's something the left is very good at, but seemingly forgot to do this time.
