This is a country almost entirely urbanized with hardly any wild habitat for the wolf to hunt in. So they do a lot of hunting in people's backyard. Killing sheep and dogs. They hunt frequently so damage is large.
Even a single case is very impactful. I recently saw footage of 3 wolves tearing apart somebody's dog. To the owner, that is devastating. Next, this is spread on Facebook, and soon the town is outraged. Surely you understand this won't last very long, somebody is going to take care of that wolf if it happens a few more times.
I love wolves, I want them to come back and want them to thrive. But at least for the Netherlands, it just doesn't work. We don't have the natural habitat.
And in any case most attacks on pets and humans are by wolf-dog hybrid which are much more aggressive (and less fearful of humans) than wolves.
So more people die in car crashes?. Good idea
Fun fact, trying to cull coyotes can actually cause the population to boom. They're remarkably adaptable creatures and very smart, to boot.
