I've never gotten the impression that Ulbricht was a psychopath or anything similar. He always came across as a naive idealist, caught way over their head in a conspiracy they never expected to succeed. He openly admits in his diary that he practiced terrible OpSec, and didn't care much.
This article doesn't make him look like an idealist at all. It makes him look like an entrepreneur that cares about success about all else. The idealism seemed to come later, as a justification.
