Sure, maybe it’s members wouldn’t do that between themselves, but they would definitely understand what deceit means, it’s quite a simple concept, much like violence.
It is not clear to me what you mean by: What kind of thinking does humanity not own?
Thinking is not something that humanity owns.

Nobody owns any thinking.
