"Whith in 2 minutes, the prey is dead" that`s highly unusual. With an older prey it takes at least half an hour and often the prey is partly eaten alive.
Eurasian wolves are more prone to be Maneaters more than American wolves. Old World wolves grew up with people. When people came to the America's they had standoff distance weapons so wolves learned to keep their distance. When they lose their fear of people where hunting is banned they start snatching pets and children with toddlers being easy prey and they tend to target children, women and the elderly. That's why its important to maintain at least light hunting. Bears are the same way. Its better they avoid people than become problem animals that end up being culled by wildlife rangers. Some people are repulsed by the idea of allowing hunting and don't understand without it far more animals end up having to be destroyed even for things like getting into the trash. For the animals sake its better that apex predators view people as dangerous and keep a safe distance away from people. I don't like the idea of killing animals that haven't bothered people but the precise reason they avoid people is that they view them as a threat.
Wolves in The Netherlands behave differently! They sleep in (urban) gardens, walk towards people, and are losing their fear for human beings. Netherland is too crowded and the situation will become dangerous in the future.
