Just today I read about the natives from North Sentinel Island, which are known for killing intruders. Can you understand how they don’t doubt about why they should kill visitors? If yes, then you found a natural part of human psychology that is largely suppressed in modern society. Fact is, humans had and have little problem with killing if they feel it‘s necessary. During the time of the second world war, the eradication of “bad people” happened in a lot of places because societies had different standards. Edit: I don’t mean to compare to make equal. Of course, we should understand the different situations that led to putting innocent people into camps and learn individual lessons.
