But the Wolves, have they already attacked men in the reality ?
No.
The idea that wolves are a threat to people beyond rare flukes or the occasional loss of livestock is a comical farce.
Bears, on the other hand, often put people on the menu.
How often is often?
I'd be surprised if there weren't more people killed and eaten by other people in NA than there were people eaten by bears.
Although, recently a man killed a young cougar with his bare hands in the United States.
That was fit young man killing a 30-40 pound juvenile, barely counts.
73-year old Daniel M'Mburugu killing an adult leopard that attacked him while he was farming, by shoving his arm down it's throat and ripping out it's tongue, was far more impressive.
