This does not explain it, qnd trying to do so through biology is the wrong angle. This issue is purely a cultural one, not a biological one, but this is not popular to investigate because 1. it's considered impossible to solve and 2. brings up difficult questions regarding cultural relativity that aren't appreciated in the modern academic Anglosphere. I'm continuously surprised that even on HN this comes up so often. A phenomenon is presented which is orders of magnitude more common in one culture than another, yet what is reached for is a biological, tech, or otherwise "hard science" explanation. In this case, the phenomenon is one of publically inflicting harm on others at a cost and no gain to themselves. I guess it has to do with the community (understandably!) having a strong tendency to approach everything from a STEM PoV when it comes to all but a small number of (mostly US-specific, policy or economic) topics. Just to prevent misunderstandings here, culture here doesn't mean the culture of a nation but of (much smaller) communities, in 2023.
