Honor means a lot of different things. And it has been used to commit so many different crimes against minorities.
I think nowadays in the western culture it means individual honor. It means to be trustworthy and to stand by your word. By the classic saying: “A gentleman can settle the bill later”.
The way late stage capitalism goes, honor culture will be left behind. Where every individual is reduced to a number, the concept is disappearing. You pay first before pumping gas. And the only time your wow matters is in the court when you say you won’t lie.
