Bloodlust is one thing, but the dehumanization is just far worse. Maybe they go hand in hand - you can't want to see someone die unless you think of them as inhuman.
There's something about social media where it has been amplifying this dehumanization as well. So another layer of sadness where it feels like we could have, should have prevented this. Like an asteroid strike or a global pandemic, it feels like one of those things that should never happen until it does. I remember looking at 80000hours and thinking, nah... nuclear warfare will never happen, let's focus on AI.
