Wolves and other animals do not attack people because they are afraid based on their experience with people. This is good. I prefer that animals be afraid of humans. The problem is (and will be worse in future) that we no longer threaten or harass these animals. As they learn not to be afraid of humans, they will become dangerous to humans. Therefore, it is beneficial to both man and beast that we humans occasionally assert our dominance, and, yes, harass them. So next time you see a coyote or a wolf, toss a rock in its general direction. You cannot tame them, but “kindness” may make them dangerous enough to harm humans and thus “need killing.”
