They aren’t demons. It’s mostly a cross between greedy, senile, and just stupid.
Whenever I see somebody make the face that both Strozk and Bankman-fried made, I don’t see those faces as that being of a human being. It is too malevolent to be that of a normal human being on their own.
It comes across as something more than just sociopathic or psychotic.
I vote for Reptilian aliens.
If they aren’t the real thing they act just like they are.
