No. The guy he "wanted to kill" was a moderator who didn't even steal from him. A FBI agent (huray, my taxes) pretended to be a drug lord for over 2yrs convincing Ross he should kill some moderator with lies about he wanting to take over silkroad or something, and then staged a mock assassination. All that for no tangible investigative benefit other then strengthen their 2yr old bro-bond.
That agent didn't even contribute to the actual arrest. Go read wired write up of the whole thing. It's better than most fiction books. Pure comedy.
Also, the current silk road is a honeypot set up by the Feds. That's why 1) they screwed up on validating transactions (it's not their money) and 2) they want after the stolen funds.
