As usual I have trouble modelling what it's like to be a person like this. I'm not beyond violence against my enemies or even taking pleasure in revenge, but at least I acknowledge that that's not the ideal scenario.
I don't want to kill fascists or billionaires, I want them to live in the world we created and admit we were right. I know we're going to have to kill a lot of them, but that doesn't make it good.
So seeing an actual genociderie come out and say "I want these people, their families, their children, dead, for no other reason than it gives me pleasure and expands my power" makes me not angry, but disoriented and nauseous.
What makes a soul twist like this. It's not normal, it's not right. It's worse than an illness, it's a rot.
