What concepts or beliefs are frowned upon across all world cultures?

It's fair to say that there isn't really one. All the cultures in the world end up having a different view on every subject. Murder is frowned upon in most cultures, but in a time of crisis or war, murder may be honored as a great accomplishment (it was such in a few dynasties of China and other cultures) Answer: cannibalism, lying, or stealing.

Altho I think that cannibalism has to be the worst and is frowned upon EVERYWHERE Actually some cultures were based off of cannibalism. It's ultimately where the concept came from: cultures emphasizing the use of it. Lying may be frowned upon, but there isn't a person who doesn't do it, so it is almost as much a part of the culture as it is frowned upon by the culture.As for stealing, when a culture is at war, stealing from another country is encouraged, and only frowned upon by those who feel victimized or sympathetic.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
