In Benedict Arnold’s case it was a commission in the British Army, and 10,000 pounds (in modern currency, millions). There’s a certain mindset that makes someone crave money and position above everything else…
Eric D. Lehman, author of Homegrown Terror: Benedict Arnold and the Burning of New London…spent time looking over Arnold’s letters and other first-hand accounts.
“Some seemed to point to him ‘lacking feeling,’ i.e. sociopathic, but others showed him having too much feeling—he couldn’t control his temper. The number one thing I found across all of them was his selfish ambition, which came from a profound lack of self-esteem as a child and young man,” Lehman says.
Oh, and he also lived lavishly, far beyond his means, was tied up in legal cases, and was married to a much younger woman (18 to Benedict’s 38) — who also happened to be a British spy — Peggy Shippen.
I’ll let you draw your own parallels.
