> amount of livestock and pets killed would be staggering

It's common sense that you shouldn't be letting your pets roam around unsupervised. We still have bears and coyotes. Wolves aren't going to change that factor significantly.

As for livestock, well, I don't believe we should be breeding livestock. Ranchers are a big problem with conservation efforts because they continuously put demands on state governments to cull predators. Not to mention that on a global scale, ranching is the #1 reason why the amazon rainforest is being destroyed. It's also unethical because, like with hunting, you're killing something unnecessarily just because it "tastes good".

> Not to mention the human attacks.

Wolf attacks are rare. Unless you're encroaching on their space by destroying habitats or removing their food, they're generally wary of people. You're far more likely to be attacked by the neighbor's dog.

Fatal dog attacks from 2005-2017 is 430. Average of 36 deaths per year.

Wolves account for only two of those over a span of 51 years.

Usually fatal attacks from wild animals are either because of rabies or because the wild animals (bears especially) got too comfortable with people because they were being fed.
