In the skeptical community, they typically put people like Rush on a spectrum (it's almost never a simple binary) between grifter and true believer. Perhaps the reason that so much ink has been used to study Elizabeth Holmes is that she's almost impossible to figure out within that spectrum.

But Rush seems to lean heavily towards true believer. If he wanted to scam people, he could have found much more remunerative ways to do it, and he certainly wouldn't have piloted the sub himself.

Rush seems like a true believer, which wouldn't influence if he was a sociopath.

Holmes was pretty clearly a grifter. I have no idea why that would be a hard question, but of course maybe you have some indicators going the other way.

sociopath != scammer

The issue here is a willful disregard for human life.
