As others have pointed out in the comments, such a sweeping statement of fact labeling an entire class of people is demonstrably incorrect. What's worse is the way you attach sociopathy to their very being., to who they "are". Perhaps rational people might agree that some billionaires exhibit sociopathic behaviors, but it's not what they "are". They are people.
Further, posts like this have a rank smell of jealousy. Everyone wants to have unlimited spending power to provide for their families and themselves. Anyone who lives in a state of lack will feel jealousy toward those who apparently don't feel the effects of scarcity in their lives. This jealousy makes them want the resources of the other person so that they can fill the emotional hole inside themselves.
Posts like this that suggest it's okay to actually take resources from another person to meet their own needs resonate with everyone suffering from a sense of lack. The arguments in the post are basically an emotional justification for taking these resources from another. That's theft. That's not any more moral than the sociopaths you decry.
I can illustrate the truth of this with a simple example. I have a close friend who lives in Nigeria. Nigerians are very poor. My friend lives on 5% of what I earn and spend during a year. To Nigerians, average Americans are billionaires. American businesses exploit Nigerians ruthlessly to produce many of the goods we buy. Some of our sociopathic billionaires participate in the exploitation, but every American who buys a good produced in a third-world country for next to nothing benefits from this exploited labor. Americans are sociopaths on a global basis. If the United Nations had a taxing power, you would see delegations from countries like Nigeria saying average Americans should be taxed out of existence too, particularly given how much higher our standard of living is compared to theirs.
Before you label me a MAGA nutcase, I would like to point out that I believe the wealthy in America are taxed far too lightly. I would enthusiastically endorse an inheritance of 90% on amounts over some reasonable amount. I would support a much higher tax rate on the highest wage earners. I like the idea of a wealth tax. Capitalism, if unchecked, will result in accumulations of vast fortunes that fail to benefit the majority. Right now, we need redistribution of our nations wealth. In short, I agree with your basic contention that we should tax billionaires much more heavily. However, your emotional arguments based on jealousy that justify outright theft -- which is the way you present it -- that is just wrong.
