Carmack is a unique case where he’s an obvious autist and pretty smart, but is a brute force pragmatist within that.

So he isn’t a sociopath, per normal understanding, but structurally he’s extremely close, and effectively he is, especially when you realize how much thought he’s put into his direction and decisions compared to most people.

The closest metaphor I can think of is like a robot that chooses to embrace Nazism because it’s pragmatic and has the highest chance for his own survival.

If conditions were different, he would go with that, but they aren’t, and so he is.

However, I will say I won’t rule him out/write him off/say he’s a terrible person, because I still assume he’s rational and not belligerent, which are two deeply entrenching and judgemental qualities. But that also being said, people like him are sometimes the most dangerous because their logic is genuine, but half baked, and so sways many more immediately dangerous people, and effectively public opinion and popular rhetoric.
