There are likely many more wolf attacks than ever known, because the wolves will take away their pray and devour almost all of it rather quickly. What's left will be scavenged within a day or so by vultures / what have you. Further, we used to regularly hunt wolves and keep dogs (Wolfhounds). As they make more human contact, they'll definitely be a lot more deaths.
That said, I think it's good / healthy to keep them around, but it's often not just the sheep that farmers are concerned about.
