Life imprisonment – with or without parole – for a non-violent crime still seems excessive. If they'd convicted him of conspiracy to murder for hiring the hitman then that's a different matter.
The non-violent crime part doesn't work for me. He acted as an enabler to countless violent crimes. That's quite clear.
He only allegedly needed to hire a hitman because the government invented the whole blackmail scenario behind it. You can't make this shit up, Silk Road was extra evil because it lead to the government creating hitmen and reasons to use them.
We need gangster hoodlums on the street because lookie here sonny, an online marketplace is dangerous and if it isn't dangerous enough well feds will make it that way.
He was steering the biggest black market on darknet, that is pretty bad
