Any animal, even a domestic dog, can be unpredictable. Coyotes and wolves are no exception; they are more likely to be unpredictable than a domestic dog, but any animal that was not raised in a human household is going to be very unpredictable when faced with human interaction. Saying wolves or coyotes are more/less likely to attack is misleading. Now there are some species that are known for being more likely to flee rather than fighting humans, such as foxes (at least where I live) and cheetahs (though attacks do occur, mostly when the animals are cornered) Wolves and coyotes are not in this category.
But the thing is, it's typically (not always, mind you) because of the human doing something silly and treating them like a dog. That's of course not always the case, but sadly a lot of wild animal attacks are due to this. (I recall a story from the past about a father trying to put his son onto a wild buffalo's back for a picture. Not cool.)
On the topic, I do adore wolves. I think conservation is important, but not allowing them to overpopulate in some areas is also important. I just hope that wolf hunters will find uses for the meat as well as bones and pelt. I don't like when a hunted animal goes mostly to waste. Also, I hope the hunting is not conducted with traps. I could never personally hunt a wolf, and would love to one day interact with either captive wolves (as in the rescued kind that are used to humans) or wolfdogs.
