Hello!

Well, even if they have never lived in the wild, this is something that they do by instinct. In fact, it is their only way to communicate since they cannot talk. Most of the time, they hiss because they are afraid and they are trying to defend or protect themselves by frightening you.

Technically, the Japanese did during World War II. Kamikaze, that is. Besides, what does it matter how they kill? All the other groups I mentioned have harmed people through poison, illnesses and chemicals.
