I'm not sure the timelines, but is the implication that Mr. Ulbricht is the original DPR (i.e. the libertarian evangelist) and not the one paying for assassinations? If so, then he can probably assist the FBI in finding the "thug" DPR, because he presumably handed control to that person, and may have some amount of corroborating evidence. That would remove the worst charges, and may mitigate sentencing for the other charges. However if Mr. Ulbricht is the one who ordered the assassinations, that is about as far from libertarian as you can get.
