Right, for a completely nihilistic fash this would be a good way to keep up the shock and horror after something like Ulvade

Alone, shooting up a July 4th parade in a ritzy part of the country might seem slightly less depraved than an elementary school. But it's the fact that this comes after Ulvade (which comes after other events, etc.) is a compounding factor that maintains the terror. And there's plenty of these chuds who want to do that, so rather than think "when will it end?" my mind is headed towards "who's next?"

They might not be able to completely exterminate their targets, but they can keep commiting acts of terror.
