I would argue that not just anyone can be a troll. Or at least, an effective one. As disgusting as the words sound, there is an art to hurting people, and most trolls are downright comic.
I wouldn't say that hurting people is always the objective of trolls.
For example, I enjoy trolling as a flat-earther from time to time. Do I really believe the earth is flat? No, but it's fun trying to defend something absurd just for the sake of honing debate skills. Sometimes I can find logical fallacies in round-earther arguments and leverage them, which is immensely satisfying.
