The sad thing is, wolves were there before the cattle. By getting rid of wolves and moving in cows, the ones being displaced were wolves and the ones changing the nature of how things worked were humans. It seems a bit unfair to go after wolves, when they were just being wolves. Did they have proof that it was even the wolves doing it...? I've seen plenty of cases where "wolves" taking down cattle wound up being feral dogs, or companion dogs that decided that killing livestock was fun.
I do wish there were better ways of dealing with all of this than killing wolves. I don't know what ranchers do and don't try, but I'd like to believe that there was more than could have been done other than destroying predators we really need.
Throughout the history of the world, there has been survival of the fittest. One predator would come in and other predators would be edged out, and some died out. This has been happening long before humans existed.
Humans are predators. we move in, we put the land to our use, and raised herds of animals for meat and products.
The wolf was in direct competition for the land, the hunting, and the safety of livestock and were eliminated.
Society changed from a society that survived as much off of wild game as livestock and hunting decreased and grazing herds increased. It balanced out to a point.
Then people felt that hunting is terrible, awful, etc, and hunting decreased further as public opinions and laws went into place. The balance was shifted again as deer and other critters started to over-populate.
And instead of encouraging hunting, the idea to re-introduce the wolf in many places took hold.
The only thing is, which is easier to catch a deer or a steer?
I guess I am not of the opinion that the only animal that has no right to live should be humans. And, I like beef. Wolves are cool. I can see them at the zoo. I don't want them in my back yard, and if I owned livestock I wouldn't want them within a couple of hundred miles.
