The thing is, the DNA of dogs and wolves are over 99 percent similar. … So while they do have physical differences, …what’s there to stop a dog from attacking the same herd it is supposed to guard? It’s breeding and training. In the human counterpart, it’s attitude, ethos and goals. Predators and protectors are totally different kinds of people, although they share many different traits. The sharing of traits, however, is the danger zone for protectors.
Or, as one friend in self-defense training joked about it to me, “The closest thing to criminals are cops. Both like to drive around in cars all day scoping out the joints, both carry guns, boss people around, and drink a lot of coffee.”

It’s definitely worth thinking through the “sharing of traits” being discussed. That whole attitude/goals thing is critical for you to turn out a decent human being after a few years of your martial arts training. If you haven’t thought about your attitude/goals, you are on the good-intentions-paved road to Bad Times. If you haven’t made conscious choices about what you want to internalize, you are careening along without intentionally steering.
