I find it interesting that a solid number of people seem to find the term predator and judge it as a negative.
I believe your reading is incorrect. I, at least, find nothing negative in the term "predator"; it's the common usage of the term that I find objectionable. People romanticize the predators of the animal world (frequently mis-identifying them - sharks, for example, are arguably much more scavengers than predators), and then apply the term "predator" to humans given to aggression whose methods and motives are entirely different. That's the problem.
