Wow, didn’t know that the entire civilized world except the US has absolutely no desire to kill each other, and all of the underdeveloped countries are full of bloodthirsty assassins.
Guess the very similar culture of Japan, Italy and Australia must be the cause.
It almost feels like the countries with high homicide rate despite the gun laws could have some correlation to being less civilized places with high corruption and/or inefficient law enforcement, but you definitely know better than me I guess.
