Tbh, I used that phrasing specifically because you were snippy about someone else making a claim based on their own experience and I was trying to prod you about the evidence you’re using.
When people kill each other “for no reason,” there’s often still a reason (though not an excuse)- territory in the case of gang or murder of romantic partners, protection or survivor’s benefits for your own family for soldiers killing in war, or people accidentally letting a killer instinct loose during play for people who get into brawls or similar. Even horrific crimes like genocide are committed out of a dual protective of kin/and aggressive of outsiders instinct.
The Wikipedia lists possible reasons, but we don’t actually know why animals do this when it’s actively harmful to them yet.
I don’t see how that supports that humans are one of a few species that kills for no reason, if we know that other animals kill in scenarios where it hurts them and we don’t actually commonly kill each other for no reason.
