Yeah, Sri Lanka for me personally is a sobering reminder that even culture/philosophy considered very peaceful can engage in worst atrocities when pushed enough. People are just people at their core, far from flawless we all crave to be.

You can't see it as a tourist there (at least I couldn't, but I didn't travel to north where most bad stuff happened). But generally this ancient mindset of 'not losing the face' can only lead to misery and desperation down the path, no matter the location. It seems its slowly dying which should be a net gain for societies still harboring it
