Wolves generally aren't even a threat to an adult human, it's mostly just prejudice. Unlike adult tigers I must say...
I ask from ignorance, but... if a medium sized dog could be a threat to an adult human, shouldn't wolves be the same?
Now that someone has mentioned the sound wolves made at death in Divine Divinity, I must admit that sometimes gets a bit unpleasant.
Try to find information about how hard it is to spot wolves in countries where there are plenty. (hint: you're only slightly more likely to find wolves as you are dragons). Wolves avoid humans, for good reason.
The thing with wolves is that even though a pack of wolves would have no problem at all taking on a lone human, they just don't. Humans just simply aren't on their menu. This *used* to be different at one point in time where due to all the wars there were human corpses aplenty lying all over the place, around that time wolves got a taste for human meat. Over time they unlearned this again (going extinct in most of the EU kinda tends to do that and as far as I'm aware it's never been an issue elsewhere either) as such the idea of attacking humans just doesn't cross their minds.
Note also that if you live in Europe you likely already have wolves visiting your country on a semi-regular basis (there's packs living in Germany and France and lone wolves have been spotted in Belgium) and within 10 years (and that is a very generous timespan) they will be pretty much all over the EU again (at least the mainland).
The only people that this might bother is idiots that don't manage to protect their pets or livestock. Also most (European) countries with wolves have reimbursement programs for livestock killed by wolves. Of course there's enough idiots that rather kill everything than adapt (which is why foxes are hated so much, learn to protect your goddamn chickens), but eh, the only absolute in the universe is human stupidity.
