What would you call someone who suffers directly from another man's success?

Context: talking about how Steve Jobs undermined and betrayed his best friend from college, Daniel Kottke. He did not give Kottke shares during Apple's IPO in 1980, and he succeeded while Kottke was left in the dust.

Thank you.
