One of the distinguishing hallmarks of North American wolves, especially Canadian Greys, is that while, yes, they have to eat (!), they also kill for fun. If something is there to kill, whether they are hungry or not, they’ll kill it if they think they can.
My brother-in-law is a rancher in western Wyoming and has seen this behavior more times than he cares to think about. He occasionally has real problems with them in regards to his herds.
For my money, I think I’ll take the opinion of someone who knows what he’s talking about.

There was a FReeper whose name I cannot recall, who posted images of just that. From the air, what the wolves had done to a herd of elk was even more astonishing as it happened in a large snow covered meadow.
We got along fine without wolves. They should never have been reintroduced. It’s part of the ecoterrorist Rewilding plan to stack n pack us into cities.
