Ross Ulbricht (Silk Road founder) talks at RNC convention

What good has done his pardon? Was it done out of policy, or just because Ulbricht paid for it with his hidden stash of crypto? Is trying to buy hitmen to assassinate someone something that Ulbricht regrets and will never try again?

(It is weird to say "a person you don't like politically" after that very person made everyone the same night at the RNC conference pledge allegiance to himself and to win by any means necessary, including cheating. Is "destroying democracy" a political disagreement we should get over with?)
