We want to feel on top of others, so we makes them feel weak by being cruel to them.

If we weren't cruel to each other, some inventions wouldn't have been created.

That's true.
In today's world it's more of a common activity to be rude, rather than in the past where it's like 'do it once and you get a death sentence'

People (governments, rulers, authority figures, etc) say they want a better world, yet they do things like this, and allow brutality?
