Idk a lot about the Samurai of Japan’s past, but I think you’re on to something because they too had a concept similar to izzat, it was called mienai (face) and Meiyo (honor/reputation). If they were insulted publicly by a lower ranking samurai or any commoner, or if Samurai felt like his honor was called into question in any way, the Samurai had no choice but to attack and usually kill the person who disrespected him publicly, because if he didn’t, his reputation would be publicly destroyed, it would shame he and his family in the eyes of the rest of the community, and there was no coming back from that shame so you either manned up and killed/maimed the offender on the spot or else you were fucked.
